Ancilary file missing?

Hi, I’m running the nesting suite on monsoon and I’ve run into some error during ‘um_recon’. A file is missing but I don’t have much idea of what is wrong beyond that:

/var/spool/PBS/mom_priv/jobs/3283027.xcs00.SC: line 103: ./ancil_versions: No such file or directory
2023-06-12T19:06:04Z CRITICAL - failed/EXIT

Thank you for the help
Russell
