Where is the maximum number of failed login attempts configured?

Hello !
I use Codeigniter 4 model with some validation rules and messages using protected $validationRules and $validationMessages (https://codeigniter4.github.io/userguide...ating-data).
I want to retrieve error messages on update but I don't succeed whereas the model respect the rules correctly (no effective update into the database if the rule isn't respected).
I tried this kind of thing in my Controller wich is called by an "ajax-javascript" function :

Error dump:

mysqli_sql_exception #1062
Duplicate entry 'john' for key 'users.username'

A part of my code:

When to create a composer package and when is it indicated to create a module?

Hi guy have ever used ci4 with Docker

I just finished my first ci4 app
Basically its backend app and frontend i use it was angular 12

I deployed both of  to the host and work very well

I need to khnow any one works with Docker 

These days in modern app use docker before deployment

I am setting a flag like this in __construct()
$_SESSION['iUploadImage']=0;
Then in _init() I am running
        if ($_SESSION['iUploadImage']==0)  //check to see if already transferred
        {
            $this->MyModel->get_image();  //gets images from s3
            $_SESSION['iUploadImage']=1;  //the files have been transferred
        }

But what I am finding is that $_SESSION['iUploadImage'] keeps getting set back to 0. The goal of this code its to only upload the images once. Any idea why this happens?

Hi all,
I have a somewhat odd problem with Sessions.  I am using the latest version of CI4, and the session handler in the .ENV is set to use the file handler.

Not every page, but sometimes, (especially if the page is refreshed) I get a Fatal Error....
Fatal error: Uncaught ErrorException: touch(): Unable to create file NULL/ci_session5oabivgbpg3ouudg0op9746292et2ql9

Now if I echo WRITEPATH I get the website root/writable - which is accurate and correct, but the file handler is putting the session files into /public/NULL/ and I am struggling to understand why. I haven't touched or replaced the session handler, nor the path to which it uses.

The writable folder contains a folder called Sessions, which have been chmod'ed to the correct values, but CI isn't using it. Can any one offer any suggestions as to what is happening, and more importantly how to correct it. I have had a search around, but haven't found anything.  If the worst comes to the worst, I'll change to the database handler.

I am keeping user's images of documents in an S3 bucket. When they first login I get all of their images and download them to my server. They are getting put into /app/assets/uploads/ etc. I am concerned about keeping user images mixed in with my code. I am using CI3 and Docker. Can anyone recommend a better place to keep user's images and tell me how I can create a path to these files in CI3?
