When submitting pbqff to a slurm queue, the following error is printed in the pbqff.log file:
thread 'main' panicked at /home/brent/.cargo/git/checkouts/psqs-bb7f245cb9c9f2af/2b4e5c7/src/queue/slurm.rs:142:17: assertion failed: fields.len() == 8

Investigating the issue in slurm.rs, reveals that it checks squeue -u $USER for 8 fields, but the present compute cluster will potentially print 9 fields due to an additional whitespace in the (REASON) portion of squeue:
JOBID PARTITION NAME USER ST TIME NODES NODELIST(REASON)
