Auto Label "My Workflows" fails to load — describe_workflow_interface 500 error

Hi all — running into a workflow-loading issue in Auto Label and wanted to check if others have seen this. I have a published workflow (Input → Object Detection Model → Dataset Upload → Outputs) that works fine via the API, but fails when selected through Auto Label’s “My Workflows” tab.

What happens: On selection, it briefly shows “Not compatible,” then quickly switches to “Failed to load workflow interface.” Underneath, there’s a 500 error on the describe_workflow_interface endpoint.

Tried so far: renamed output blocks, made a simplified version of the workflow (no Dataset Upload block) — same error both times. Confirmed the workflow works fine via direct API calls. Hard-refreshed and checked status.roboflow.com — no outages.

Seems isolated to the “My Workflows” selector itself, not the workflow or a real compatibility issue. Searched the forum and AI assistant, found nothing matching — Any pointers on what might be causing the 500 on describe_workflow_interface, or a workaround, would be really helpful.
