SaltStack: MySQL returner save less data into Database table columns

[xtc14]

I'm trying to modify the existing SaltStack MySQL returner to only save a handful of data instead of the default columns
(| fun | jid | return | id | success | full_ret) to something like

(| fun | jid | return | id | success)

The file I'm working on is this one:
https://github.com/saltstack/salt/blob/m...s/mysql.py

I installed this python module python3-mysqldb so Salt can communicate with MySQL v8.0.25

The part that I modified (line 313)

  try:
        with _get_serv(ret, commit=True) as cur:
            sql = """INSERT INTO `salt_returns`
                     (`fun`, `jid`, `id`, `success`)
                     VALUES (%s, %s, %s, %s)"""

But I'm getting this error when running something like
salt '*' test.ping --return mysql

Error:
2021-07-01 11:46:05,693 [salt.minion      :2055][ERROR   ][16794] The return failed for job 20210701174605511891: not all arguments converted during string formatting

During handling of the above exception, another exception occurred:

I'm guessing it comes down to how each column in the table was defined, but I'm not sure where to make further modifications to write data in only those columns.
