Why would I get : 'KeyError: ''name'''

Why would I get : ‘KeyError: ‘‘name’’’. Workflow is not having syntax errors and renders fine in editor as well.

Error message is not clear and not sure what to check in workflow.

Can you post your workflow definition file here? Someone can then see and point out anything obvious then
