Incorrect ref returns ambiguous 'failed with exit code 1' error

[miriam-lam-sndk]

Fetching the repository
  "C:\Program Files\Git\bin\git.exe" -c protocol.version=2 fetch --no-tags --prune --no-recurse-submodules --depth=1 origin +refs/heads/badrefname!:refs/remotes/origin/badrefname!+refs/tags/badrefname!:refs/tags/badrefname!
  The process 'C:\Program Files\Git\bin\git.exe' failed with exit code 1

When given an incorrect or malformed ref, the action does not return the actual git error message. I expect an error like error: pathspec 'badrefname!' did not match any file(s) known to git
