[Error] Matter and WiFi connectivity

[MiguelGomesEstevao]

I'm currently trying to send data from my ESP32 to Google Home using the Matter Protocol.
I managed to get it on my Google Home app but it appears as offline, so I tried to connect the device using the WiFi library so it can send data do the endpoint (Don't know if that helps, I was hoping to get some insight about that too).

However, this error message appears on my serial monitor log when I run the code.
I've been trying to fix this for days. Is the WiFi loop interfering with the creation of the endpoint somehow?
I'm sending my code below. I would be glad if someone could help me. Thank you in advance.

You should not connect Matter devices with WiFi library - Matter library should take care of it and reconnect automatically. I think that you should debug logs from Matter.

I got to define the ssid and password somewhere in my code right?
I've been searching the source code and the examples but I can't find any example of that.
Im able to detect my matter device and add it to my Google Home App but it says my device is offline.

During pairing, credentials of WiFi where you are currently connected are send from your phone to Matter device. Matter then uses it to join network. Maybe your network is causing problems? Try changing SSID or network to 2.4GHz. I would also look through logs carefully - there should be info about trying to connect to WiFi during pair process

[MiguelGomesEstevao]

You were right, it is able to pair the WiFi.

The problem now is that the attribute::update is not being able to update the endpoint.
Do you know what might be causing this?
Sorry for making lots of questions, I really need to implement this for a work.
I think I configured everything well looking at the examples that are available.

I'll send my code below in case of need. Thank you in advance.
