Azure Function App throws internal server error.

Question

After repeated attempts with running function app and connecting with fivetran we constantly get either internal server error or module not found : requests , even though we have requests in our requirements.txt.

[Error] Executed 'Functions.function' (Failed, Id=id, Duration=3ms)

Would are we possibly doing wrong? Any leads will be helpful.

Thanks

@Antara Das As per the error module not found : requests' looks like you have not installed the module requests. But as you have confirmed that you have mentioned requests in your requirements.txt file but I will suggest you to review your application insights logs to verify if the module was installed correctly.

To troubleshoot these types of errors you can always refer to this document.

If you have any requirement where you need to use any other packages that are not predefined in the functions then you need to add the names or names along with versions of the required packages to the requirements.txt file. Please refer to this document for more details

Your requirement.txt file will be as below per the exception but in case if you are using any other packages then please make sure that you have defined the same.
