Bulk workflow creation/validation

I’m trying to use a new endpoint for workflow creation/validation to copy already existing workflow.
I’m trying the following, but I only get this Invalid request payload. Refer to the REST API documentation and try again., which is unclear. Could you guide me in the correct direction?
