How to fix 'Error: Encountered an error (InternalServerError) from host runtime'?

Question

I finally figured out how to deploy an azure function from my local project to my cloud on VSCode, but when I expand the Function App dropdown and the Functions dropdown and try to execute the function from VSCode, I get an error: Error: Encountered an error (InternalServerError) from host runtime

There are no other logs AND the same message appears on the azure website. I know the functions work because the trigger URLs display the response in my browser. but for whatever reason both the Azure website and VSCode cannot execute the function.

The function I am using is the 'hello-world' function from the Azure Functions course module on Microsoft Learn, I did not customize anything.

This question is related to the following Learning Module

Hello @dhdorr,
To resolve the error encountered an error (InternalServerError) from host runtime' when running your Azure Function, start by checking that all necessary environment variables are correctly set missing or incorrect ones can cause runtime failures. Even if it seems like there are no logs, recheck the Azure portal, as logs might offer clues. Review the function’s configuration and code, especially if it's a basic "hello-world" function, to ensure everything is structured and set up correctly.

If the issue continues, try redeploying the function, as this can sometimes fix deployment-related issues. It's also a good idea to check the Azure status page in case there's a service outage affecting your function. Additionally, make sure you're using the latest version of the Azure Functions extension in Visual Studio Code to avoid compatibility problems.

Finally, double-check all configuration settings in the Azure Portal, including triggers and bindings, to confirm that everything is properly configured. Azure Functions require a valid storage account. If the storage account is misconfigured, it can cause runtime failures. Ensure that AzureWebJobsStorage is correctly set in Application Settings.
