That error comes at an verry simple methode : add

function add(){
        $d = $this->addupd('a');
        //var_dump($d);
        $db = db_connect();

        $db->table(self::$table)->insert($d);
        $this->liste();
}


Nothing had changed recently ...   At first I was thinking of hacking and a thirt party success to introduce code in my applicaiton.  But this is only an hypothese

Did you download and install the newest version of CodeIgniter 4 ?

What did you Try? What did you Get? What did you Expect?

It is not really the last one but it is the CI4

One more information . all the app is brocken. I can't login anymore. On every page I have this message.

---

I have the same code on local with the same database (I dump it for save) and it works well.

I can add one more information. I dont know if that helps
But my table already had 127 recored and the key was tinyint(4) I notice that when I test on other environement. I change this to int

Maybe I break something in this database. 128 in int(4) !!!
