Hi we've noticed this error again. Upon further investigation, it is a certain instance that causes it.
Please do the following:
1. Try to edit your community builder password BUT misspell one of the passwords.
EX: Password = password | Verify Password = passsword (notice the extra "s") | Current Password = your current password
2. If that doesn't throw the error please try: Password = password | Verify Password = password | Current Password = MISSPELL THIS
Please let me know if there is a solution to this so the user isn't getting the error "CALL TO A MEMBER FUNCTION GET()", instead they're redirected back to the edit page with a message perhaps. Thank you!
