resolves #42510
Issue: When I run the test. get this error:
I get the same error when I try to run TestErrCheck, the test I based mine off of.
There is an issue where error objects are being flattened
stripping them of all their details(stack traces, user hints).
This introduces a linter that will find remaining cases of
unwrapped errors and prevent more cases from occurring.
Release note: None
