"list index out of range" when inputting a 16 channel latest image to the sampler

[liuxiaolong98]

The usual practice is to input an EmptyLatentImage, which has a channel of 4. However, when inputting an image from channel 16 (such as connecting to EmptySD3LantentImage), an error will occur(list index out of range);

However, in line 379 of node. py, the sampler supports 16 channel images：
if c==16: orig_x=latent_image['samples'] lat_processor2 = LATENT_PROCESSOR_COMFY() orig_x=lat_processor2.go_back(orig_x) orig_x=orig_x.to(device, dtype=dtype_model)

By investigating the internal code, the problem occurred in lines 255 and 266 of the sampling. py file, with a t_id of 21 and a timesteps list length of 21. Using the command t=timesteps [t_idx] would result in the above error
