cet-is » art

Hello,

Below is a complete output from an art run. The error message gives no clue on where the problem is.

This was for a non-trivial job setup with multiple paths, filters, output modules...
And with configuration spread out over several fcl files.
I could not find the mistake until I ran the program under
gdb and walked up the stack frame to figure out the offender.
Turns out, there was a typo in a line that set the output file name

outputs.crvHitsOutput.fileName: "crvStopsToHitsConversion.root"

Please provide a more informative error message.
Andrei
