Error Deploying Azure Function from VS Code: 'No HTTP triggers found'

Question

Error Deploying Azure Function from VS Code: 'No HTTP triggers found'

idea-seeds 25

I am trying to overwrite deploy code that I was previously able to deploy to an Azure Function App using VS Code, but I am unable to deploy it. So, I tried to investigate by creating new sample code and new Function App on the Azure. Even it's brand new one, the deployment seems to be successful, but the console in VS Code displays "No HTTP triggers found," and it appears that the files themselves are not present on Azure.

What can I do to successfully deploy a Function App from VS Code?

What I have tried:

(Note: Some details like the Function App name have been replaced with [******REDACTED******].)

Start VS Code.
To create a new template, perform the following actions in the VS Code command palette:
1. Select > Azure Functions: Create New Project.
2. Specify a particular folder as the project save location.
3. Choose "Python" as the language.
4. For the Python execution environment, select "Skip virtual environment."
5. Choose "HTTP trigger" as the template.
6. Specify "http_trigger" as the function name for the template.
7. Set the auth level to "FUNCTION."
8. Select "Open in current window."
Run func host start to confirm that it can run in the local environment.
To deploy the newly created template, I created a new Function App by performing the following actions in the VS Code command palette:
1. Select > Azure Functions: Create Function App in Azure (advanced).
2. Specify a name for the Function App.
3. Choose "Linux Consumption" as the type.
4. Select "Japan East" as the region.
5. Choose "Python 3.11" as the stack.
6. Select my resource group for the Function App.
7. Choose "Create new storage account."
8. Specify a name for the storage account.
9. Select "Skip for now" for Application Insights.
10. Select "Create Assigned identity" for Assigned identity.

The output displayed in VS Code after executing these steps was as follows:

16:11:16: Failed to get latest templates: The operation was aborted. Rejecting from abort signal callback while making request.
16:15:41: Creating user assigned identity "[******REDACTED******]" in location "Japan East"...
16:15:42: Successfully created user assigned identity "[******REDACTED******]".
16:15:42: Ensuring App Service plan "[******REDACTED******]" exists...
16:15:42: Creating App Service plan "[******REDACTED******]"...
16:15:44: Successfully created App Service plan "[******REDACTED******]".
16:15:44: Creating storage account "[******REDACTED******]" in location "Japan East" with sku "Standard_LRS"...
16:16:09: Successfully created storage account "[******REDACTED******]".
16:16:10: Role assignment "Storage Blob Data Owner" created for the storageAccounts resource "[******REDACTED******]".
16:16:10: Creating new function app "[******REDACTED******]"...
16:16:34: Successfully created function app "[******REDACTED******]": https://[******REDACTED******].azurewebsites.net

Select > Azure Functions: Deploy to Function App.
1. Choose the previously created Function App name.
2. When warned that it will overwrite and cannot be undone, select "Deploy."

As a result, the following logs were displayed in the VS Code output, indicating that no HTTP Trigger function exists.

What steps can I take to investigate this further, or solve this?

@idea-seeds

I have replicated the same steps in my environment, and the deployment worked as expected.

To help pinpoint the difference, can you please confirm:

Does your function_app.py have a function with a trigger (like @app.function_name(trigger=...))?

Are function.json and __init__.py files present inside your project?

Was the project created using an Azure Functions template or manually?

Are you using the Python v4 programming model?

Any custom changes made to the folder structure or files?

Your responses will help me suggest the next steps

@Sai Prabhu Naveen Parimi

Thank you for your reply. I appreciate your assistance in troubleshooting this issue. Here are my responses to your questions:

Does your function_app.py have a function with a trigger (like @app.function_name(trigger=...))?
- Yes, I think it does. My python code contains @app.route(route="http_trigger_test") so I believe the function_app.py have a function with a trigger. For more details, below is the code generated by the > Azure Functions: Create New Project command in VS Code so please see it.
Are function.json and init.py files present inside your project?
- The function.json file exists, but the __init__.py file is not present.
Was the project created using an Azure Functions template or manually?
- I believe the project was created using an Azure Functions template, as I executed the > Azure Functions: Create New Project command in VS Code and did not modify any code or files.
Are you using the Python v4 programming model?
- I believe that I'm using Python v2 programming model. Here is the structure of files. (v4 is for Node.js I think.)

functionTesting 
  ├─ .funcignore
  ├─ .gitignore
  ├─ function.json
  ├─ function_app.py
  ├─ host.json
  ├─ local.settings.json
  ├─ requirements.txt
  ├─ .vscode
  │    ├─ extensions.json
  │    ├─ launch.json
  │    ├─ settings.json
  │    └─ tasks.json
  └─ __pycache__
        └─ tasks.json

And, here are the codes that I generated and attempted to deploy:

function_app.py


import azure.functions as func
import logging

app = func.FunctionApp(http_auth_level=func.AuthLevel.FUNCTION)

@app.route(route="http_trigger_test")
def http_trigger_test(req: func.HttpRequest) -> func.HttpResponse:
    logging.info('Python HTTP trigger function processed a request.')

    name = req.params.get('name')
    if not name:
        try:
            req_body = req.get_json()
        except ValueError:
            pass
        else:
            name = req_body.get('name')

    if name:
        return func.HttpResponse(f"Hello, {name}. This HTTP triggered function executed successfully.")
    else:
        return func.HttpResponse(
             "This HTTP triggered function executed successfully. Pass a name in the query string or in the request body for a personalized response.",
             status_code=200
        )

function.json

It's empty file.

host.json

  "version": "2.0",
  "logging": {
    "applicationInsights": {
     "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[4.*, 5.0.0)"
  }
}

@idea-seeds

The root cause was that the AzureWebJobsStorage setting was missing in the Function App’s configuration. Here's what we did:

In the Azure Portal, we went to the customer’s Function App → Configuration → Application settings, and added the key:

AzureWebJobsStorage with the connection string from the linked Storage Account.

After redeploying from VS Code, we tested the function URL in the browser and it responded with:

"This HTTP triggered function executed successfully. Pass a name in the query string..."

Everything worked fine after that.

Sharing this here in case it helps others running into the same “No HTTP triggers found” issue when deploying from VS Code.

Thank you very much for your detailed help. It was very helpful.

For future reference and for those who might face similar issues, I would like to note down the steps you provided in a bit more detail.

1. Create New Project

Start VS Code.

To create a new template, perform the following actions in the VS Code command palette:

Select > Azure Functions: Create New Project.

Specify a particular folder as the project save location.

Choose "Python" as the language.

For the Python execution environment, select "Skip virtual environment."

Choose "HTTP trigger" as the template.

Specify "http_trigger" as the function name for the template.

Set the auth level to "FUNCTION."

Select "Open in current window."

To create a new template, perform the following actions in the VS Code command palette:

Select > Azure Functions: Create New Project.

Specify a particular folder as the project save location.

Choose "Python" as the language.

For the Python execution environment, select "Skip virtual environment."

Choose "HTTP trigger" as the template.

Specify "http_trigger" as the function name for the template.

Set the auth level to "FUNCTION."

Select "Open in current window."

2. Check the Code

Run func host start to confirm that it can run in the local environment.

3. Create new Function App

I selected > Azure Functions: Create Function App in Azure (advanced) from VS Code to create a new Function App. However, I believe it would be the same if I created a new Function App from the Azure portal. I created a new Function App by performing the following actions in the VS Code command palette:

Select > Azure Functions: Create Function App in Azure (advanced).

Specify a name for the Function App.

Choose "Linux Consumption" as the type.

Select "Japan East" as the region.

Choose "Python 3.11" as the stack.

Select my resource group for the Function App.

Choose "Create new storage account."

Specify a name for the storage account.

Select "Skip for now" for Application Insights.

Select "Create Assigned identity" for Assigned identity.

4. Copy the Storage Account Information to Associate with the Function App

Access the Azure portal and open the storage account that you want to associate with the Function App. This is often created together with the Function App.

In the left panel, select "Access keys" under "Security & networking."

Display the connection string for key1 and click the copy button on the screen to copy the string content. (Please note that you should not copy it by dragging and dropping.)

5. Set the Environment Variable for the Function App

Access the Azure portal and open the Function App created in step 1. In the left panel, select "Configuration" under "Settings."

Click the "New application setting" button in the "Application settings" tab. Enter AzureWebJobsStorage for the name, paste the connection string you copied earlier for the value, and click the "Save" button.

Once again, click the "Save" button in the environment variable list screen.

Return to the overview screen of the Function App.

Click the restart button to restart the Function App.

Click the "New application setting" button in the "Application settings" tab. Enter AzureWebJobsStorage for the name, paste the connection string you copied earlier for the value, and click the "Save" button.

Once again, click the "Save" button in the environment variable list screen.

Return to the overview screen of the Function App.

Click the restart button to restart the Function App.

Now, the storage account and the Function App are linked, and the Function App is working correctly.
