Exercise creation: Error 400 on submission

[seyfeb]

Sometimes, but not always, I get an error 400 logged when clicking the submit exercise button in the exercise creation dialog. The button is then grayed out and no exercise is created. Creating the exercise requires starting from scratch.

Edit: Sometimes the exercise is created with the error but the notes section is missing.

wger version 2.3.0a2
