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
Finally found a fix for that, is posted on GitHub repo issues section of library issue 503 google cloud sdk php
