Google credential failures recognised when wrapped in another error

You'll notice
Useful2 Signal1
Elsewhere

Google credential failures buried inside another error are now identified properly.

What

Google authentication failures are now detected by walking the chain of nested causes rather than only inspecting the top-level error, so a wrapped credential failure is classified correctly instead of surfacing as a generic error. One more matching message was added to the existing set.

Details
  • Matched messages include Could not load the default credentials, Could not refresh access token and invalid_grant, plus one further substring.
  • The top-level value no longer has to be an Error instance for the check to fire.
Evidence

Could not refresh access token

Strings lifted out of the shipped bundle, so the claim above can be checked against them.
