Copy/paste of pictures fail since 16.3.0

Good day everyone!

I’m facing an issue since I updated to XWiki 16.3 (Docker image).

Collaborative editing is lightning fast but when I copy / paste a picture, it displays a black square and, checking the source of the page, it gives me :

[[image:data:image/gif;base64,R0lGODlhDgAOAIAAAAAAAP///yH5BAAAAAAALAAAAAAOAA4AAAIMhI+py+0Po5y02qsKADs=]]

The picture was uploaded (in the attachments at the bottom) and I have the same error when I switch to “not collaborative editing” (xwiki-realtime OFF in CKEditor plugins).

Hopefully I’ll find the solution soon!

Ouch, I confirm that I could reproduce and I’ve created Loading...

Sorry about that, we’re going to fix it real soon.

Thanks for the reactivity (as usual :muscle:), as the picture is uploaded, it’s quite easy to update the black square with it.

Hello everyone,
I have the same problem (black square when inserting images), but with XWiki version 16.6.0.
The source code also looks like antony’s:
[[image:data:image/gif;base64,R0lGODlhDgAOAIAAAAAAAP///yH5BAAAAAAALAAAAAAOAA4AAAIMhI+py+0Po5y02qsKADs=]]
According to the article above, the problem should be solved with 16.3.1, but for me it isn’t. Any ideas?
Thanks a lot!

Hello.I’ve tried to reproduce Loading... on XWiki &6.6.0 by following the exact steps from the description and couldn’t reproduce.

You’ll need to tell us more about how to reproduce the problem you have.

Thanks for the quick feedback.
I am trying to insert a screenshot in the editor WYSIWYG mode (created in Windows with Snipping Tool). Then a black square appears:

In source mode I see this:
[[image:data:image/gif;base64,R0lGODlhDgAOAIAAAAAAAP///yH5BAAAAAAALAAAAAAOAA4AAAIMhI+py+0Po5y02qsKADs=]]

I can provide log files if necessary.

Thanks

How?

In my test I did some drag and drop and the wiki markup I got was [[image:Screenshot 2024-03-19 at 13.54.06.png]] (ie not a data URI content).

Same problem with drag and drop. I dropped a small png file (5KB) and the result is the same. Black square and source code the same as above.
First try from above was with “Strg+V”.
No problem if I upload attachments.

I have looked at the request for the upload with the developer tools of the browser and the result actually looks good:

The returned URL for the image is also valid. When I call this up in the browser, I end up at the corresponding image.

What else can I check?
