Description:

No integration seems to work.
For example, I got an error by using the giphy integration. (https://github.com/FinndropStudios/GifRocket)
Additional: No one can create a message, when alias is empty in user settings.

@ph1p can you go to the integration's history and show a screenshot of the result that errors out?
