Have a quick question about my html

Question

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

Answer 1

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.
