The process_name field in the CreateElementsWorkflow API docs is marked as allowing 150 characters, when DataImport.name only allows 100 characters. This field is not used by the frontend, but an API request can cause a 500 error:

cli.request('CreateElementsWorkflow', body={"corpus": "…", "process_name": "a" * 150})
