It's only generating the first frame of a video, and then returning an error?

[KarmaMole]

The masking process works and it generates all the mask frames for my video (8 seconds at 25 fps), but then it generates the first image of the new video and stops with an error message:

inpainting fragment 1 / 1
Aspect ratio has been corrected from 512x512 to 384x680
Use cn inpaint instead of sd inpaint
*** object of type 'NoneType' has no len() ***

Any help much appreciated!

Hello. Which versions you use:

• a1111 webui
• controlnet
• animatediff
• replacer

Also can you provide more information. Because I don't have this error
