Error using `Load Image Batch` node

[howon52]

Hello, and thank you for the great addition to comfyui.

I am getting the following error while trying a simple batch load.

Prompt executed in 0.00 seconds
got prompt
Traceback (most recent call last):
  File "/mnt/d/Github_D/ComfyUI/execution.py", line 257, in execute

    input = input.replace("%width%", str(images[0].shape[1]))
TypeError: 'NoneType' object is not subscriptable

Steps to reproduce:

• Placed images in ./ComfyUI/input/
• Simple nodes to preview image as below.

(Saw issue #25 but your sample workflow link doesn't seem to work anymore)

Hmm. Wonder if it's cause of the list support thing that was added. I'll take a look here in a moment. Could be update to TEXT_TYPE

[WASasquatch]

Hmm. I still can't to get this to give me a NoneType. Well I can, but only when I have removed a file from the folder that it previous indexed as existing. I updated the node to actually state if it found no file, but I'm still unsure where the issue is coming from for people.

Did you by chance add or remove files from the input dir while it was running?

[howon52]

I think I didn't, but just to check, rebooted ComfyUI now and am still getting the error...
Should my files in ./ComfyUI/input/ directory be of specific format or filenames?

[WASasquatch]

It should only gather file paths of valid image formats. Unless there is a format I have included that PIL doesn't read, but I don't think so. I will double check.

Another issue. Oudl be maybe the path? Maybe try a full path to a folder.

Just for information purposes to see if I can reproduce, what sort of file types do you have in there?

[howon52]

Tried rebooting everything then using full path to folder, seem to have done the job.
Thank you for the support, and sorry that took longer than expected!
