Seedance + image reference + Gemini + HTTP 404

Hello Adobe team. I think there is an issue with Firefly video generation using Seedance 2.0 / Seedance 2.0 Fast with image references.

Text-to-video works normally, but any image-to-video generation fails. I tested multiple reference images, including an original character, a screenshot version, and a normal photo of a cat. All fail with the same error.

Error message:
“Gemini classification API returned HTTP 404. Model gemini-3.1-flash-lite-preview was not found or the project does not have access to it.”

This happens on both the iPhone Firefly app and the desktop browser version.
