[2.42.0] Bug with impersonated account token refresh #1850
Description
After updating from 2.41.1 to 2.42.0 I get this issue:
File "C:\...\.venv\Lib\site-packages\google\auth\transport\requests.py", line 535, in request
self.credentials.before_request(auth_request, method, url, request_headers)

TypeError: 'str' object is not callableIt seems this commit changed the refresh logic of impersonated account credentials at exactly this line: 36ecb1d#diff-9fb6744f480c88b7964f845792d2d930c9a7048caee2ba4931dc2c899c623cb6L289
Reverting back to 2.41.1 fixes it.
Python: 3.13.9
