I'm in windowns 10. I was developing my python azure function in vscode and test it in local host. Everything was fine until recently. I tried to start my azure functions, but I got error messages like below:

Exception has occurred: ModuleNotFoundError
No module named 'grpc_tools'
  File "c:\users\myusername\appdata\roaming\npm\node_modules\azure-functions-core-tools\bin\workers\python\3.7\windows\x64\grpc\__init__.py", line 2034, in <module>
    import grpc_tools
  File "c:\users\myusername\appdata\roaming\npm\node_modules\azure-functions-core-tools\bin\workers\python\3.7\windows\x64\azure_functions_worker\dispatcher.py", line 16, in <module>
    import grpc
  File "c:\users\myusername\appdata\roaming\npm\node_modules\azure-functions-core-tools\bin\workers\python\3.7\windows\x64\azure_functions_worker\main.py", line 7, in <module>
    from . import dispatcher
  File "c:\users\myusername\appdata\roaming\npm\node_modules\azure-functions-core-tools\bin\workers\python\3.7\windows\x64\worker.py", line 59, in <module>
    from azure_functions_worker import main

I have not changed anything since last time I tested my azure function. Have no idea why I got the error messsage. Does anyone know what the error message mean? what cold be the solution to the issue?

Something wrong with the azure-functions-core-tools? The problem is I have not changed anything at all. But now it stopped working for no reason. Really appreciate it if anyone can help. Thanks.

Running func start from the cli works for me; running from VS Code still produces errors.

Also, trying to manually install the packages works; however, I consider this a workaround. Also you will be going down the rabbit hole, as every time you add a package, some other one will not work.

I had the same issue start popping up yesterday after a few months of not working with Azure Functions and on a new laptop.

I found that you can disable the exception alerts in the Visual Studio Code debugger.

Which can be found in the bottom left corner while debugging under breakpoints

By default, Uncaught Exceptions and User Uncaught Exceptions are checked: uncheck them and that will prevent the debugger from showing exceptions.
