when executing
workflow.create_dispatch with dispatch_inputs parameters, only "False" is returned when there are issues with formatting or input names

in Workflow.py , create_dispatch function

    status, _, _ = self._requester.requestJson(
        "POST", f"{self.url}/dispatches", input={"ref": ref, "inputs": inputs}
    )
    return status == 204

this should at least print the real error code , that would be a lot more informative
