Unable to run python program on Azure Function App, despite successful execution locally

Question

I encountered an issue while trying to run a Python program on Azure Function App. The program, which integrates with Google API and Notion API for calendar synchronization, runs successfully locally on my machine. However, when deployed to Azure Function App, it fails to run. I would like to seek assistance from the community on how to resolve this problem. Here are the specific details and error messages I encountered:

1. The Python program runs without any errors and functions properly on my local machine.
2. When deploying the program to Azure Function App, it fails to execute.
3. I suspect there might be configuration or dependency issues specific to the Azure environment causing the program to fail.

I would greatly appreciate any guidance, advice, or suggestions on resolving this issue and successfully running the program on Azure Function App. Thank you for your assistance!

from google.oauth2.service_account import Credentials
from googleapiclient.errors import HttpError
from googleapiclient.discovery import build

However, when deployed to Azure Function App, it fails to run.

Please follow the below action plans for now:

1. Could you please check if all the required libraries and dependencies for Google API and Notion API are installed on the Azure Function App environment. Follow the steps mentioned here
2. Please check if the suggestion provided here helps ?
3. Could you please enable the Application insight logs for the FunctionApp and check if there are any invocation exceptions. You can enabled the AppInsights as explained here.You can enabled the AppInsights as explained here.
4. Please check Functions metrics for the HTTP Server Errors at the time of the issue.
   
5. Please check the Function App detectors by navigating to the Diagnose and Solve Problems section in the Azure Portal for the Functions as shown below: You can rely on the Function Executions and Errors setting:
   
6. You can also query the FunctionLogs as shown below:
   

Note: If none of the above steps help, Please share the below details over an email at AzCommunity@microsoft.com ( with subject "Attn: Naveen") and include the below details:
