[Bug]: [Wii U] Sending 280-character-long message returns Unprocessable Entity

What happened?

I was trying to send a post with a message that had 280 characters, exactly the character limit, but just enough for it to be accepted. I pressed on the "Send" button, and got greeted with a white screen, with a loading animation (or spinner) and very small grey text saying "Unprocessable Entity". Nothing changed afterwards, the only thing I can do is to exit out of Juxtaposition by pressing the HOME button.

What did you expect to happen?

I expected for it to load for a bit and to go back to Juxtaposition with the post sent, as usual.

Steps to reproduce?

1. Power on Wii U with Inkay installed
2. Click on Miiverse
3. Go to any community
4. Click on "+ Post"
5. Fill in the input text with 280 characters of text
6. Click on "Post"
