Im not that experienced in coding (like at all so I'll try to be as helpfull as possible)
Okay so when I try to give a user an organization this error occures. The same error shows up when i swap the organization with an already existing one by going on the tab "users" --> press on a user --> click on organization --> then press on change --> change with an already existing one --> and then the error shows (heres a picture)

It does change the organization when i refresh the page... but yeah i just wanted to know if im doing anything wrong in particular. I hope my issue is kind of understandable.
Big thanks in advance 🙂
