I changed url to external url

'drivers' => [
Spatie\OpenTelemetry\Drivers\HttpDriver::class => [
'url' => 'https://jaeger.dev.xxx.pk/api/traces',
],
],

but when in postman i use this route I get this error
{
"message": "Undefined array key "basic_auth"",
"exception": "ErrorException",
"file": "/app/vendor/spatie/laravel-open-telemetry/src/Drivers/HttpDriver.php",
"line": 19,

<?php

namespace Spatie\OpenTelemetry\Drivers;

use Illuminate\Http\Client\Factory;
use Illuminate\Support\Facades\Http;
use Spatie\OpenTelemetry\Support\Span;

class HttpDriver implements Driver
{
protected array $options = [];

public function sendSpan(Span $span)
{
    $payload = [$span->toArray()];

    $promise = Http::async()->asJson()
        ->withHeaders($this->options['headers'] ?? [])
        ->when($this->options['basic_auth'], function (Factory $client) {
            $client->withBasicAuth(
                $this->options['basic_auth']['username'],
                $this->options['basic_auth']['password'],
            );
        })
        ->post($this->options['url'], $payload);

    $promise->wait();
