🐛 Fixed auth errors (#300)

Resolves issue #299.

int | str is used instead of updating the type to only "str" because the API change appears to have been introduced quietly and may revert in the future. Since the exact type of these fields is not critical for the library, supporting both types provides a safer and more resilient approach.
