Note this error has been raised with unsupported version of Slurm (21.08.5).

Logs from slurmrestd were not provided by user but this error was probably initially caused by a 404 from this service, due to API version 0.0.39 being unsupported by Slurm 21.08.5. Then this is probably a duplicate of #321.
