[BUG] Unexpected token λ in JSON at position 0

Action config

Error message

It seems all is successful, but it somehow fails with a very weird error message. It doesn't seem to happen locally with npx firebase deploy. The action usually works, this seems to be intermittent. When I re-try the action, it usually succeeds.

✔  hosting[project8372]: release complete 
  
✔  Deploy complete!
