Arvados

Steps to reproduce:

1. Write a workflow with a separate step file where both use an input with the same enum type.
2. Register that workflow in Arvados:

   arvados-cwl-runner --create-workflow pathv2.cwl

3. Submit the registered workflow to Arvados:

   arvados-cwl-runner --submit PATH_V2_CWL_UUID path.yml

arvados-cwl-runner crashes with:

ERROR Workflow execution failed                                                                                                [117/1341]

ERROR Workflow error, try again with --debug for more information:
Workflow did not return a result.

Some interesting notes:

• If you run the workflow without registering it, it works fine.
• If you run the workflow with --local instead of --submit, it works fine.
• If you define the enum type in SchemaDefRequirement, it works fine.
