Image Upload Fails on Agent Node

[paulo-coronado]

Description

When attempting to send an image (e.g. .png, .jpg etc.) to the agent node, it instantly returns the following error:

Workflow failed: Error code: 400 - {'error': {'message': 'Invalid input: Expected image type to be a supported format: .jpeg, .jpg, .png, .gif, .webp but got none.', 'type': 'invalid_request_error', 'param': 'input', 'code': None}}. (code: server_error)

---

Steps to Reproduce

1. Create a simple workflow with:

   • A Start node
   • An Agent node connected to it

2. Start a new chat.

3. Try to send an image (any supported format: .jpeg, .jpg, .png, etc.).

4. Observe that the workflow immediately fails with the error above.

Additional Notes

• Tried multiple image formats (.jpeg, .png, .webp) — same result.
• Text-only or .pdf inputs work perfectly.

Weirdly enough, the issue seems to have fixed itself. Not sure what happened, but it’s working fine now! 😅
