can i resolve this issue

I tried changing updateUser method from user actions and trying to find any mistakes in AccountProfile, but what solved my problem was deleting the collections from mongodb. (You can also delete the users from clerk in order to reuse your email)
In my case I had my mongoose user schema variable set as userName instead of all lowercase username. I decided to change it half way to username but because the db already had a user collection with userName, it was not allowing me to create / update. Hopefully this will help any of those who encounter this error.
