Deploy function from VS code to function app in Azure: No HTTP triggers found.

Question

Deploy function from VS code to function app in Azure: No HTTP triggers found.

Youssef Awad 25

I have been trying to deploy a simple function in VS code to my function app in Azure. I keep getting the message No HTTP triggers found. and the function does not show up in Azure. I have already reviewed all other posts with the same error and none of the suggestions worked for me.

I created the app function in Azure Portal

Hosting plan: Consumption
Operating system: Linux
Runtime stack: python
Version: 3.11

In VS code, I created an empty folder

Azure Functions: Create New Project
- Selected folder
- Selected python
- Selected HTTP trigger template
- Python interpreter: 3.11
- Authorization level: FUNCTION

Now I have the base template project created, completely unchanged and want to deploy to Azure

function_app.py:

import azure.functions as func


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

@app.route(route="test_http")
def test_http(req: func.HttpRequest) -> func.HttpResponse:

    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
        )

I tried looking through "Functions that are not triggering" in "Diagnose and solve problems" but that did not help

I tried turning on Application Insights to look at the Log Stream but there was nothing helpful there.

I cannot figure out why it's not working. I have created the function app like the documentation says and created the project in VS code exactly as the template provided.

Any help would be greatly appreciated

Hi @Youssef Awad ,

Root Cause:

You're using the Python v2 programming model (FunctionApp in function_app.py), which doesn't generate a function.json file like the v1 model. Azure Functions on Linux support v2 model, but only if configured correctly.

If the required app settings are missing or misconfigured, the Azure platform won’t detect your HTTP triggers.

Go to your Function App > Configuration >Environment Variables > Application Settings in Azure Portal and ensure the following settings exist:

FUNCTIONS_WORKER_RUNTIME : python

PYTHON_ENABLE_WORKER_EXTENSIONS : 1

If PYTHON_ENABLE_WORKER_EXTENSIONS is missing, add it manually.

qna

qqq

As you can see, Function is working locally.

abcdeee use the Azure CLI to deploy the Function app to azure Portal:

func azure functionapp publish <FunctionAppName>

kshfksjdhf Once deployment is done. Check the portal

After applying the fixes above, your function should appear in Azure Portal under Functions, and you'll be able to access the trigger URL.

Final Output: As you can check below Trigger function is live on Portal as well.

I am still not able to deploy to azure

In bash, I tried running the the below command:

func azure functionapp publish sadek-func-app

And also tried this:

func azure functionapp publish sadek-func-app --python --build remote

Got the following error:

Azure Functions Core Tools does not support this deployment path. Please configure the app to deploy from a remote package using the steps here: https://aka.ms/deployfromurl

I then tried to upload my zip package to Azure blob container and tried to deploy that way by using Azure Cloud Shell in the Azure environment

I checked my environment variables and have WEBSITE_RUN_FROM_PACKAGE defined as the <URL> for my package in the blob container

I ran the following command:

az functionapp deployment source config-zip --resource-group mygroup --name myapp --src https://mystorage.blob.core.windows.net/test-func?<sas-token>

still I get the same error:

The Azure CLI does not support this deployment path. Please configure the app to deploy from a remote package using the steps here: https://aka.ms/deployfromurl

Hi @Youssef Awad ,

Apologies for the delayed response, and thank you for the detailed input. After performing a root cause analysis, I've concluded that the issue is due to the following:

If WEBSITE_RUN_FROM_PACKAGE is set to a remote URL, Azure assumes you’re doing remote package deployment, which disables other deployment methods like:

func azure functionapp publish, az functionapp deployment source config-zip

Try the below Workaround to fix this:

Revert to Local Zip Deploy (recommended for dev)

Remove the remote URL setting: Go to Azure Portal > Function App > Configuration > Application Settings

Delete the WEBSITE_RUN_FROM_PACKAGE entry (or set it to "1" to use internal zip deploy).

Save and Restart the Function App**

Deploy using Core Tools:

func azure functionapp publish sadek-func-app

If WEBSITE_RUN_FROM_PACKAGE is set to a remote URL, local deployment methods like func azure functionapp publish will fail.

Since you're just deploying from VS Code or terminal manually, I recommend (clear WEBSITE_RUN_FROM_PACKAGE) and return to normal zip deploy using Core Tools.

Hope it helps!

So, it turns out that this is caused by a free tier limitation. As soon as I upgraded to basic tier and created a new function app using flex consumption (instead of consumption), everything worked.

I recommend creating a ticket to fix this for the free tier so that people don't have to spend money just to create a basic function.

Hi @Youssef Awad ,

If you're deploying a Python Azure Function (v2 programming model using function_app.py) to a Linux Consumption Plan, and encountering:

No HTTP triggers found

or your function not appearing in the Azure Portal. This is a known behavior due to Oryx build limitations and remote build constraints on Linux Consumption for the Python v2 model.

As you see below, Function app is working Locally.

Follow the below workaround to resolve it:

Here’s what worked for me:

Deploy using Blob Storage + WEBSITE_RUN_FROM_PACKAGE setting.

Create Resources (Linux Consumption Plan)

RESOURCE_GROUP=rg-func-demo LOCATION=eastus STORAGE_ACCOUNT=funcdemostorage$RANDOM FUNCTION_APP=sadek-func-app-$RANDOM az group create --name $RESOURCE_GROUP --location $LOCATION az storage account create --name $STORAGE_ACCOUNT --location $LOCATION --resource-group $RESOURCE_GROUP --sku Standard_LRS az functionapp create --name $FUNCTION_APP --storage-account $STORAGE_ACCOUNT --resource-group $RESOURCE_GROUP --consumption-plan-location $LOCATION --runtime python --runtime-version 3.11 --functions-version 4 --os-type Linux

Zip Your Function App

From inside your function directory (with function_app.py, host.json, and requirements.txt):

Compress-Archive -Path * -DestinationPath functionapp.zip

Upload ZIP to Blob Storage

Run this command from the directory where functionapp.zip is located:

az storage container create --name functiondeploy --account-name $STORAGE_ACCOUNT az storage blob upload --account-name $STORAGE_ACCOUNT --container-name functiondeploy --file functionapp.zip --name functionapp.zip

After Upload: Generate a SAS Token & URL

SAS_TOKEN=$(az storage blob generate-sas --account-name $STORAGE_ACCOUNT --container-name functiondeploy --name functionapp.zip --permissions r --expiry $(date -u -d "1 day" '+%Y-%m-%dT%H:%MZ') --output tsv) ZIP_URL="https://${STORAGE_ACCOUNT}.blob.core.windows.net/functiondeploy/functionapp.zip?$SAS_TOKEN" echo $ZIP_URL

Configure Function App to Run from ZIP:

az functionapp config appsettings set --name $FUNCTION_APP --resource-group $RESOURCE_GROUP --settings WEBSITE_RUN_FROM_PACKAGE="https://${STORAGE_ACCOUNT}.blob.core.windows.net/functiondeploy/functionapp.zip?$SAS_TOKEN"

Restart the Function App:

az functionapp restart --name $FUNCTION_APP --resource-group $RESOURCE_GROUP

Check the Azure Portal

Go to Azure Portal → Your Function App → Functions

Your HTTP-triggered function (e.g., test_http) should now appear

You can invoke it using the Function URL

For more details, please refer the following documentation:Deploy from package, Python v2 model intro. Hope it helps!
