Multiple images are not being returned (empty output)

[jamesblackwell]

See the end of the output from the workflow below, two images in the ComfyUI temp output but replicate output is nothing

Strangely, it works with multiple images on some workflows but not others, even though the same save node is used

Problem workflow:

Do you have a link to the prediction so I can debug?

[fofr]

Some suggested fixes:

• make sure "return_temp_files" is set to True to return any previews as well
• make sure "randomise_seeds" is True (sometimes ComfyUI will avoid repeating work, so if the seed matches it might skip some steps or avoid generating)

im facing the same issue, here is a prediction from your model https://replicate.com/p/0q1xa8rm41rgm0chxhh9dh1hv8
