We found that users have a dependency on an undocumented behavior of the permissive yaml library that was changed here.
Using a block like below caused the yaml parsing to fail the whole

would cause the failure.If not done, customers upgrading to the new server version would see mapping error when cache is lost on authenticato restart.
