I am facing issue with azure function deployment as the azure functions returns the below error.

Result: Failure Exception: ModuleNotFoundError: No module named 'requests'. Please check the requirements.txt file for the missing module.

@Niren Adhikary (NAD) Thanks for reaching out and apology for the delay. Please let me know if you are still facing the issue.

Sharing for community:
As you are using requests module in your azure function and when there is a missing dependency, you should see the below error message in application insights that you have configured for your function app. In case if the changes are not saved correctly to your local file then the deployed code will not have the new changes.
ModuleNotFoundError: No module named 'requests' looks like you have not installed the module requests.

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

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

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.

For your reference, I will suggest you to review this article which will can help you to monitor azure function. Once you have set it up you can see the above error in application insights. You can also see these exceptions in the storage account that you have configured on your function app.

Please refer to Azure function python document to get more familiar with the development.
