Custom validation failed for node: image - Invalid image file

[swapnil281095]

Hello,

I am working on image generation task using Replicate's elixir code for API call. Since I cannot send locally stored image as a request to Replicate API. I have updated the comfyUI workflow json and replaced local image path with hosted image's path url and below is the error I am getting:

I am new with the comfyUI and may be I have used an incorrect node.

Please can you share a link to your prediction so I can debug

I ran this into replicate playground https://replicate.com/fofr/any-comfyui-workflow?prediction=09kzy7ndqhrgp0cgm5gvresysg

Thank you, I've found the bug.

Partial fix here, but I'm going to do a more airtight one shortly:

@fofr , Thank you for the efforts. I now understood the issue, earlier code didn't supported workflow with duplicate urls. When I tried executing with different urls, it worked and moving forward it can also support duplicate urls.
