-Subject: [PATCH 33/74] make tests tolerant to authlib 1.5.2 error messages
- (#18390)
-
-authlib 1.5.2 now single-quotes error messages in the claims, causing
-three tests to fail.
-
-Replace the comparison with a regex that accepts both single or double
-quotes.
-
-This succeeds the tests with both authlib 1.5.1 and 1.5.2.
-
-See https://github.com/NixOS/nixpkgs/pull/402797 for context.
