Description

It appears that DUNE configuration requires a job FHiCL file to include sam_dune.fcl, or else the submitted job terminates with art code 90 and:

$ cat larStage0.err
Failed to parse the configuration file 'subrun_wrapper.fcl' with exception
---- Parse error BEGIN
  Local lookup error
  ---- Can't find key BEGIN
    dune_tfile_metadata (at part "dune_tfile_metadata")
  ---- Can't find key END
  at line 9, character 29, of file "./Stage0.fcl" 
  included from line 1 of file "./subrun_wrapper.fcl" 

  services.TFileMetadataDUNE: @local::dune_tfile_metadata
                              ^
---- Parse error END

This must be seldom a problem because sam_dune.fcl is included by services_dune.fcl, which in turn is commonly included in user configuration files.
The reason I tripped into this problem is that my configuration is spread across some local files, and rather than copying all of them to the job, I choose to use fhicl-dump utility to generate the configuration to submit. Since my job was not explicitly configuring the metadata, that utility removed the unused configuration that is instead required by the wrapping configuration.

A solution is to modify the wrapper to include the necessary configuration files before including user's job configuration, with a line like:

#include "sam_dune.fcl"

Gianluca:

I stumbled across this ticket. I think you have to make an assignment if you help with such issues. We should address our fcl more generally but, for now, I think you have include services_dune.fcl or patch things locally as you suggest. I am closing this but please reopen if you are in need of a specific change.
