What happened?

If you have a conversation (Messages tab) open on Wii U and try to send a screenshot when making a post it will cause a error with the page similar to the "404 Not Found" error with the bandwidth image.

What did you expect to happen?

Sending a message with a screenshot should successfully send a screenshot attatched to the post. like in the example below. (Juxt Web)

Steps to reproduce?

Add a friend on friend list. check their juxt profile via the applet. click the message button in the left side of the follow button.
go to a game and suspend the game via the home button. try to attatch and send a screenshot in the messsage post.
then the 422 error should happen when clicking post.

Other relevant information. (OPTIONAL)

Here's how the error looks like on Portal.
