    Not sure what this means here.

  • It means that a callback was called, and then a callback was called again... hmm...

    Definitely looks like a bug to me.

  • And the picture doesn't crop or anything, it just simply uploads and converts the image extension.

    EDIT: Only happens when uploading GIF images. If that helps.


    This fixes the throw new Error('Can\'t set headers after they are sent.');

    It still doesn't explain why the im.convert is failing though. I tested with a few small gifs on my test environment with convertToPng turned on and it works fine. So I couldn't reproduce that error. Can you provide a link to the gif you are using @trevor?

  • Its any GIF, so it might be Imagemagick but... I'm not quite sure.

    Let me update the application to the latest commit to see what it does now.
