Unable to readImage() using clipboard-manager

[simonsanchezart]

Describe the bug

I've installed clipboard-manager
I want to be able to read images from the clipboard.

I have this in my capabilities.json:

    "clipboard-manager:allow-read-image",
    "clipboard-manager:allow-read-text"

I'm attempting to read an image like this:

      case "KeyV":
        if (e.ctrlKey) {
          const any = await readImage();
          console.log(any);
        }
        break;

Getting the following error when 'pasting' an image
Uncaught (in promise) The clipboard contents were not available in the requested format or the clipboard is empty.

This happens when the clipboard is not empty, and with an image is in a clipboard, as tested in https://evercoder.github.io/clipboard-inspector/

await readText(); works fine when I just have plain text.

Reproduction

No response

Expected behavior

I expected await readImage(); to not throw an error if I have an image in my clipboard.

It seems to work for me here, could you provide a minimal reproducible example that we could test on?

Thanks for the repro, I can reproduce this now. So this is about reading copied image files right?

That's correct, or copying images directly (from a browser, for example) which I haven't tried yet
