No API interface shows after deployment

Question

No API interface shows after deployment

Jinda Wang 45

Hi All,

I wrote some API interface, and they are working fine in my local machine. But when I tried to deployment to Azure cloud, the terminal was shown "Deployment successful" and "No HTTP triggers found".

This resulted in me not being able to find any of the interfaces I wrote in the dashboard. I don't know whether some configuration files I've written wrong.

local.settings.json

{
  "IsEncrypted": false,
  "Values": {
    "AzureWebJobsStorage": "UseDevelopmentStorage=true",
    "FUNCTIONS_WORKER_RUNTIME": "python",
    "AzureWebJobsFeatureFlags": "EnableWorkerIndexing"
  }
}

host.json

{
  "version": "2.0",
  "logging": {
    "applicationInsights": {
      "samplingSettings": {
        "isEnabled": true,
        "excludedTypes": "Request"
      }
    }
  },
  "extensionBundle": {
    "id": "Microsoft.Azure.Functions.ExtensionBundle",
    "version": "[3.*, 4.0.0)"
  }
}

@Jinda Wang Welcome to Microsoft Q&A Forum, Thank you for posting your query here!

I understand that you have a python based Azure Function App and post deployment you are unable to see the Triggers.

How are you performing the deployment from VS code ?

Please follow the below suggestions step by step:

Please check the AzureWebJobsStorage setting in local.settings.json.
You need to update the value to the Azure Storage connection string:

DefaultEndpointsProtocol=https;AccountName=<ACCOUNT NAME>;AccountKey=<ACCOUNT KEY>;EndpointSuffix=core.windows.net

Also ensure the same connectionstring is placed in the AzureWebJobsStorage App settings in Azure Function App portal.

Please try to deploy using the zip deployment method and check if that helps. You can use the below command to publish your function app:

func azure functionapp publish <APP_NAME>

Note that you need to run the above publish command by navigating to that folder where you have your python application file.

Hope this helps.

If none of the above plan helps, please let me know. I will share few more action plans to isolate this issue. Awaiting your reply.

@navba-MSFT Thank you for answer.

I updated the AzureWebJobsStorage field in local.settings.json, and deploy my code by the following way in VSCode. Unfortunately, it still shown Deployment successful. I noticed that the code was already deployed to remote site but there were still no triggers in the portal. :(

Also, I tried deploying it by command func azure functionapp publish <APP_NAME>, another error was raised.

Should I modify any configuration files else?

Thank you!

@Jinda Wang Thanks for your reply. Please install the Azure CLI and configure to use it with VS Code as explained in this article. Then try running the func azure functionapp publish <APP_NAME> command.

@Jinda Wang Thanks for getting back and sharing an update.
.
Let's take a step back and try creating a new FunctionApp project in VSCode and then try pasting your code in it and then deploy.

Follow the below article:

@navba-MSFT Sincerely appreciate your assistance once again!

My deployed code finally shows triggers in the Azure Portal!

However, I still don't know the root cause of the previous deployment failure.

@Jinda Wang Thanks for your reply. I am glad that when using a new function app template you were able to deploy your code with the triggers.
.
In order to identify the root cause for previous deployment failure, it requires a closer troubleshooting. If you could share the proof of concept (smaller version of your function app), I would be happy to test this at my end and check if I can deploy with the triggers.
