Have a quick question about my html
https://github.com/FasterJake/Flask-Login-register/tree/main/templates Here is what I am working with currently. My problem is when I go to do the check if a username exists or not I get an error but I am not sure what to do about it. "sqlalchemy.exc.IntegrityError: (sqlite3.IntegrityError) UNIQUE constraint failed: user.Username [SQL: INSERT INTO user ("Username", password) VALUES (?, ?)] [parameters: ('jake013245', b'$2b$12$iGUE1Qo1Ld6u216YhB2JIOz2.szktpEKbo.Dxb6B4Sa6EGELFcQdW')] (Background on this error at: https://sqlalche.me/e/14/gkpj)" I think it is flagging at line 102. Any insight would be great. haha

Read the error message.
"Unique constraint failed"
"Insert into user"
The error occurs, because your code is trying to add a new row to the user table, but it already has a row with the same username (probably), so insertion is failing.
