Start by reproducing the failure through the chef push entry point with a Policyfile-based cookbook containing a Ruby syntax error, using the reported Policyfile.lock.json output as context. Trace the error reporting path to determine why the cookbook file and syntax location are omitted; done means the failure identifies where the syntax error occurred.
