Hello  I'm trying a modification of the Point-to-point routing sample at

My job is failing with jobinfo messages: "Submitted.", "Executing...", "Failed."
and taskfailedeventargs: "Unable to complete operation." /-2146233088/0x80131500 (no inner exception)

What are some techniques I can use to get some more information about the reason why the job failed?

Would the .dat files in the subfolders of %temp%\arcgisruntime_xxxx be helpful to me?  How can they be read?  Any other ideas?
