send wifi credentials to ESP32 via web Bluetooth

Question

Im trying to send wifi credentials to esp32 BLE device using web bluetooth. I'm getting the error Received invalid JSON for every combination I've tried so far. Right now the code is simple and goes:

const connectToDeviceAndSubscribeToUpdates = async () => {
    const device = await navigator.bluetooth.requestDevice({
        // filers: ["ESP32-E89F6DD0DF34"],
        acceptAllDevices: true,
        optionalServices: ["0000aaaa-ead2-11e7-80c1-9a214cf093ae"],
    });

    let server = await device.gatt.connect();
    const service = await server.getPrimaryService(
        "0000aaaa-ead2-11e7-80c1-9a214cf093ae"
    );

    let characteristic = await service.getCharacteristic(
        "00005555-ead2-11e7-80c1-9a214cf093ae"
    );
    console.log(characteristic);

    var thing = await characteristic.readValue();
    var encoder = new TextEncoderStream();
    let data = { ssidPrim: "", pwPrim: "", ssidSec: "", pwSec: "" };
    await characteristic.writeValueWithoutResponse(
        encoder.encode(JSON.stringify(data))
    );
    console.log(response);
};

document.getElementById("connect").addEventListener("click", (e) => {
    connectToDeviceAndSubscribeToUpdates();
});

the JSON let data = { ssidPrim: "", pwPrim: "", ssidSec: "", pwSec: "" }; has been modified to all shapes for example {ssid:'',pass:''} {ssid:'',password:''} {ssid:'',passwd:''} {information:[{ssidPrim:'',passPrim:''}]} etc. (the empty quotes were filled).

Also I've tried to send it with the methods writeValue 'writeValueWithResponseandwriteValueWithoutResponse` all the same results.

I've read a lot of tutorials but moste of them in C, C++ and I could translate the information into JavaScript.

Right now I'll try any ideas.

The ESP module is Olimex ESP32-WROOM-32F.

I'm using this function in windows powershell to read from the device

function read-com {
 $port= new-Object System.IO.Ports.SerialPort COM8,115200,None,8,one
 $port.Open()
 do {
 $line = $port.ReadLine()
 Write-Host $line 
 } while ($port.IsOpen)
 }

Theese are the information from connecting using the above funtion to sending information via web-bluetooth
