Masking Helper, ungraceful handling of "no detection"

[CptCoolArrow]

Masking Helper throws an error when it gets an image with no detection. For batch processing, especially video processing, this can be a real pain if there is a frame or two where a face is totally obscured. Does anyone have a solution? I've tried messing with the settings but without success.

Seems that this fix breaks the compatibility with the ImageListToImageBatch node, at least when there are frames with no detection.

!!! Exception during processing!!! Sizes of tensors must match except in dimension 0. Expected size 4 but got size 3 for tensor number 1 in the list.
