Error when installing MDM server


I’m currently in the process of installing the MDM server on a RHEL-9 server.
I followed the Brad Sexton guide and it’s pretty much done but, when trying to deploy it from the WebUI it fails at the step:

continue if {exists file “/var/opt/BESUEM/windows/logs/windows-mdm_opstate.json” whose(modification time of it > now - 10 * minute AND(it as string = “Initial” or it as string = “Periodic”) of path “$[‘OutputType’]” of json of it)}

I confirmed that the .json is not in the folder but cannot find the reason nor logs explaining it.

My bigfix server is a RHEL-8 with BigFig 11.1.

Any help would be appreciated.
