Summary

I launch vasp calculation with help of fireworks in offline mode on our group cluster. (Nodes cannot make network connections so online node is not an option). When fireworks tries to retrieve status of completed job (after lpad recover_offline), it fails because custodian cannot decode something:

Error message

In attached archive there is fireworks output of job. You can see that vasp job was competed successfully. Error message above is in FW_offline.json.gz.

I edited line 172, modifying RunVaspCustodian class atomate/vasp/firetasks/run_calc.py and made default gzipping False: gzip_output = self.get("gzip_output", False) This make my jobs status display as complete successfully So problem is with gzipping
