Google Cloud SDK request to vertex ai, return error 503

Im implementing the prediction ia services, using php sdk for google Cloud platform,but when im doing the request, service return 503 UNAVAILABLE code 14, but if i use a curl petition to the test the same thing, return ok results. Variable $model is like projects/{project}/locations/{location}/publishers/google/models/*

function generate_content_sample(string $model): void
{
    $predictionServiceClient = new PredictionServiceClient();

    $contentsParts = new Part();
    $contentsParts->setText("loremp ipsum"); 

    $contentsParts = [new Part()];
    $content = (new Content())
        ->setRole('user')
        ->setParts($contentsParts);

    $contents = [$content,];
    $request = (new GenerateContentRequest())
        ->setModel($model)
        ->setContents($contents);

    try {
        $response = $predictionServiceClient->generateContent($request);
        printf('Response data: %s' . PHP_EOL, $response->serializeToJsonString());
    } catch (ApiException $ex) {
        printf('Call failed with message: %s' . PHP_EOL, $ex->getMessage());
    }
}

That service is used in a controller like this

public function generate(Request $request)
{
    try {
        $vertexAIService = new VertexAIService();

        $projectId = 'Lorem ipsum';
        $locationId = 'Lorem ipsum';
        $modelId = 'Lorem ipsum';

        $formattedEndpoint = sprintf(
            "projects/%s/locations/%s/publishers/google/models/%s",
            $projectId,
            $locationId,
            $modelId
        );

        // $content = WebScrapingController::scrape($request->url);
        // $prompt = $request->prompt . ': ' . $content;

        $response = $vertexAIService->generate_content_sample($formattedEndpoint, "Lorem ipsum");

        FacadesLog::debug('Response: ' . $response);

        return response()->json([
            'response' => $response
        ]);
    } catch (Exception $e) {
        return response()->json([
            'error' => $e->getMessage()
        ], 500);
    }

Result code

Call failed with message: {

I use the oficial libraries "google/apiclient": "^2.18", "google/cloud-ai-platform": "^1.13",

Also, that code works perfectly like three or 4 days ago and now suddenly return that error
