Apache-libcloud raises 403 for Azure Blob Storage

Question

I have a celery task which copies data from one azure container to another using apache libcloud.

Task works fine but after some time I get 403 error.(For example task copies 50 files and then suddenly raises 403)

What could be the problem?

python3.8
apache-libcloud==3.3.1
celery==5.0.5

Thank you kamoloff. As you mentioned in the comment, the cause of the 403 error was trying to copy an empty file.

Alternatively, 403 error also occurs when there is a larger file size.

"The maximum file size currently supported by the Azure Storage driver is 256 MB. Uploading larger file sizes will require a code change in libcloud."
