README.md.Expected Behavior
Clicking "Generate image" on a response (the icon next to the "Read aloud" button) should generate an image based on the response.
Actual Behavior
After upgrading to v0.6.42, clicking the "Generate image" button causes an error that only states [object Object].
Generating images with the Integrations menu through the input box (Image toggle) works fine.
Steps to Reproduce
Start a normal conversation with the LMM. Ask it to describe a scene.
When the text response is generated, click the "Generate image" button (located next to the read aloud) icon.

Open WebUI gives a pop-up error that only states [object Object]
Logs & Screenshots
Browser console logs:

Additional Information
This was working prior to updating to v0.6.42, and we know Open WebUI is communicating with the image generation API as generating images through the integrations menu works as exxpected.
