Error using FileCollection.add() since version 2.3.15

[patrickvolz]

Since version 2.3.15 I get this error when trying to upload a file to sharepoint:
FileCollection.add() missing 1 required positional argument: 'content'

It works with version 2.3.14. No change in code other than the version of the Office365-REST-Python-Client package.

What could be the root cause? Thank You,

Will this ever be fixed or does anybody know a workaround.
I will try latest version to check if there is still the same problem...
