On attempting to load a KBART file into the agreements internal KB, I'm seeing the error: "Job execution failed" in the Info log

KBART file attached
Other params:
Package name: "A.P. Publications Limited"
Package source: "KBPlus"
Package reference: "1234"
Package provider: "A.P. Publications Limited"

On Slack ethan reported:

Right so it looks like the job isn't even being created
The block that throws the error:

try {
              MDC.setContextMap( jobId: "${jid}", tenantId: "${tid}" )
              jobContext.set(new JobContext( jobId: jid, tenantId: tid ))
              beginJob(jid)
              wrk()
              endJob(jid)
            } catch (Exception e) {
              failJob(jid)
              log.error ("Job execution failed", e)
              notify ('jobs:log_info', jobContext.get().tenantId, jobContext.get().jobId,  "Job execution failed")
            } finally {
              jobContext.remove()
              log.debug "Finished task with jobId ${jid} and tenantId ${tid}"
              MDC.clear()
            }
          }
