I am testing the Discourse Encrypt plugin and I notice every time I try to upload an image in the encrypted PM then I’ve got the following error popup message: Sorry, but we couldn't determine the size of the image. Maybe your image is corrupted? and the upload fail. Do I missed something?
There were some changes in the uploads pipeline in core and this was an incompatibility with the new one. I just fixed the bug and everything should work well now.
