We recently made a migration to net 6, in azure functions
And I have the following error, but I can't figure out what it is

You might want to open a support case via https://support.microsoft.com and share more details with Microsoft support team. They can help you on locating the root cause.

SnehaAgrawal-MSFT 21,506 Reputation points2023-09-06T05:59:37.1166667+00:00 @Emanuel Jiménez Thanks for reaching here! Based on the error message you provided, it seems like there is a
FileNotFoundExceptionbeing thrown in your Azure Function. The error message also mentions that the exception is being handled, but it doesn't provide any additional information about what might be causing the issue.To troubleshoot this issue, you can try the following steps:
- Check if all the required dependencies are present in your project.
- Check if the file that is being referenced in the exception message exists in the expected location.
- Check if there are any issues with the file system or permissions that might be causing the issue.
If none of these step's help, you can try enabling more detailed logging in your Azure Function to get more information about the error. Refer to this article on how to set log level for function v1 or v2.
You can also try debugging your function locally to see if you can reproduce the issue and get more information about what might be causing it.
Please let us know if issue remains.
