Exception: ConnectionError: ('Connection aborted.', OSError(107, 'Transport endpoint is not connected'))

Question

Hello good afternoon,

I have an Azure Durable Function that copies files from one storage account to another, but after an hour of copying, I get the following error in the activity function.

As they are copies of a large volume of data, I have to refresh the access_token after a while, since the files after an hour were created totally empty. Then add in the activity function the refresh token method and I get the following error.

Result: Failure
Exception: ConnectionError: ('Connection aborted.', OSError(107, 'Transport endpoint is not connected'))
