    3.0 Works perfectly. but 3.1 just right away give me a lot of errors
    - Return type mismatch between linked nodes: conditioning, received_type(CLIP) mismatch input_type(CONDITIONING) CLIPTextEncode: - Return type mismatch between linked nodes: clip, received_type(STRING) mismatch input_type(CLIP) GetImageSizeAndCount: - Return type mismatch between linked nodes: image, received_type(CONDITIONING) mismatch input_type(IMAGE) DownloadAndLoadFlorence2Model:

    ........

    and the list just incrieses for what i see the Florence model have all the input mixmatch but after comparing it to the 3.0 they seem similar sooo no clue, and they will still get trigger if i disable automatic promt
