Request guidance on error in receiving token in Laravel - laravel

Question

Greetings and Regards
I am designing an api with Laravel and using a passport for an app.
I'm having trouble logging in using the login endpoint.
The problem I encountered is as follows:
I will send the necessary parameters to the server including
client_id - grant_type - username - password - client_secret - scope:
{{server_url}}/api / v1 / login
In the login method:
After evaluating entries I send a request to oauth/token to receive theta token.
I get the error below.
GuzzleHttp\Exception\ClientException: Client error: POST
http://divar.local/oauth/token resulted in a 400 Bad Request
response: {"error":"invalid_grant","error_description":"The provided
authorization grant (e.g., authorization code, resource owner
(truncated...)
The contents of the login method
public function login()
{
$validator = Validator::make(request()->all(), [
'mobile_number' => 'required',
'password' => 'required',
]);
if ($validator->fails()) {
$response['errors'] = $validator->errors();
return response()->json($response, 401);
}
$clientOauthData = Client::where('password_client', 1)->where('name', 'Laravel Password Grant Client')->first();
$http = new \GuzzleHttp\Client;
$response = $http->post(env('APP_URL') . '/oauth/token', [
'form_params' => [
'grant_type' => 'password',
'client_id' => $clientOauthData->id,
'client_secret' => $clientOauthData->secret,
'username' => request('mobile_number'),
'password' => request('password'),
'scope' => '',
],
'headers' => [
'Accept' => 'application/json'
]
]);
$response = json_decode((string)$response->getBody(), true);
return response()->json($response, 200);
}

This is how I always proceed this request.
public function login(Request $request)
{
$this->validate($request, [
'email' => 'required|mobile_phone',
'password' => 'required|string',
]);
$http = new \GuzzleHttp\Client;
try {
$response = $http->post(config('services.passport.login_endpoint'), [
'form_params' => [
'grant_type' => 'password',
'client_id' => 'your client ID',
'client_secret' => 'secret ID,
'username' => $request->mobile_phone,
'password' => $request->password,
// 'scope' => '',
],
]);
return $response->getBody();
} catch (\GuzzleHttp\Exception\BadResponseException $e) {
if ($e->getCode() == 401) {
return response()->json(['message' => 'This action can\'t be perfomed at this time. Please try later.'], $e->getCode());
} else if ($e->getCode() == 400) {
return response()->json(['message' => 'These credentials do not match our records.'], $e->getCode());
}
return response()->json('Something went wrong on the server. Please try letar.', $e->getCode());
}
}
