Error 500 at google spreadsheets_values get method - php

Question

I read through a lot of posts but cannot find the reason or method to troubleshoot the error 500 when calling google sheet spreadsheets_values->get method.
Here is my code, very standard
header('Access-Control-Allow-Origin: https://script.google.com');
header('Access-Control-Allow-Origin: https://www.google.com');
require __DIR__ . '/vendor/autoload.php';
/**
* Returns an authorized API client.
* #return Google_Client the authorized client object
*/
function getClient()
{
$client = new Google_Client();
$client->setApplicationName('SPD Web Services');
$client->setScopes(Google_Service_Sheets::SPREADSHEETS);
$client->setAuthConfig('credentials.json');
$client->setAccessType('offline');
$client->setPrompt('select_account consent');
// Load previously authorized token from a file, if it exists.
// The file token.json stores the user's access and refresh tokens, and is
// created automatically when the authorization flow completes for the first
// time.
$tokenPath = 'token.json';
if (file_exists($tokenPath)) {
$accessToken = json_decode(file_get_contents($tokenPath), true);
$client->setAccessToken($accessToken);
}
// If there is no previous token or it's expired.
if ($client->isAccessTokenExpired()) {
// Refresh the token if possible, else fetch a new one.
if ($client->getRefreshToken()) {
$client->fetchAccessTokenWithRefreshToken($client->getRefreshToken());
} else {
// Request authorization from the user.
$authUrl = $client->createAuthUrl();
printf("Open the following link in your browser:\n%s\n", $authUrl);
print 'Enter verification code: ';
$authCode = trim(fgets(STDIN));
// Exchange authorization code for an access token.
$accessToken = $client->fetchAccessTokenWithAuthCode($authCode);
$client->setAccessToken($accessToken);
// Check to see if there was an error.
if (array_key_exists('error', $accessToken)) {
throw new Exception(join(', ', $accessToken));
}
}
// Save the token to a file.
if (!file_exists(dirname($tokenPath))) {
mkdir(dirname($tokenPath), 0700, true);
}
file_put_contents($tokenPath, json_encode($client->getAccessToken()));
}
return $client;
}
// Get the API client and construct the service object.
$client = getClient();
$service = new Google_Service_Sheets($client);
$spreadsheetId = '1mTrQp8yzioqLpr9m_2or1wLkVzvZpWYz65RJyIqxxxx';
$range = 'PABS';
$response = $service->spreadsheets_values->get($spreadsheetId, $range);
$values = $response->getValues();
if (!empty($values)) {
foreach ($values as $row) {
$abslist .= "<li>{$row[0]}</li>";
}
}
exit;
I tried to add the exit at the different line and find the error was occurred at
$response = $service->spreadsheets_values->get($spreadsheetId, $range);
Is there any error to my code? Is there any debug console allowing me to find the reason?
Best regards,
Kelvin.

Sorry for my important mistake, I didn't enable the APIs and Services from Google console.
