bug: uploading big images fails

I'm facing a very odd issue with whiteboard, depending on image size it won't sync the images or store them in the file.
Here are some logs from the backend, at the beginning what happens when I paste a small image, the file gets uploaded with no issue and the log only says "added image". After that what happens when trying to paste a big image.

All the [Object] elements in the room are missing images, excluded 2. An odd behaviour is that visually the image is shown in the screen of thw user, but not synced. When opening the whiteboard again, if one pastes the same image again the old instances will show the image again.
