Description

Starrifying self.kwargs['headers']['authorization'] in __repr__ overrides access_token in HTTPClient header when __str__ or __repr__ are called.

Possible Fixes

• Refrain from updating the value of self.kwargs['headers']['authorization'].
• Switch to deepcopy() instead of a shallow copy().

Considerations

• deepcopy() might be less performant than copy() or even json.dumps().
• Updating __repr__ so that it doesn't need to update value of self.kwargs['headers']['authorization'] might result in "uglier" pattern.
• Solution needs to be compatible with all service and HTTPClient classes.
