I'm using google slide API to connect to my project account, the connection worked perfectly, but sometime I get this error :

Fatal error: Uncaught Google_Service_Exception: { "error": { "code": 503, "message": "The service is currently unavailable.", "errors": [ { "message": "The service is currently unavailable.", "domain": "global", "reason": "backendError" } ], "status": "UNAVAILABLE" } } in /vendor/google/apiclient/src/Google/Http/REST.php:118 Stack trace: #0 /vendor/google/apiclient/src/Google/Http/REST.php(94): Google_Http_REST::decodeHttpResponse(Object(GuzzleHttp\Psr7\Response), Object(GuzzleHttp\Psr7\Request), 'Google_Service_...') #1 /vendor/google/apiclient/src/Google/Task/Runner.php(181): Google_Http_REST::doExecute(Object(GuzzleHttp\Client), Object(GuzzleHttp\Psr7\Request), 'Google_Service_...') #2 /vendor/google/apiclient/src/Google/Http/REST.php(58): Google_Task_Runner->run in /vendor/google/apiclient/src/Google/Http/REST.php on line 118

This is my getClient function Google API:

function getClient(string $SCOPES,string $CLIENT_SECRET_PATH,string $CREDENTIALS_PATH,string $APPLICATION_NAME) { $this->client->setApplicationName($APPLICATION_NAME); $this->client->setScopes($SCOPES); $this->client->setAuthConfig($CLIENT_SECRET_PATH); $this->client->setAccessType('offline'); $this->client->setApprovalPrompt('force'); $credentialsPath = $this->expandHomeDirectory($CREDENTIALS_PATH); if (file_exists($credentialsPath)) { $accessToken = json_decode(file_get_contents($credentialsPath), true); } else { $authUrl = $this->client->createAuthUrl(); printf("Open the following link in your browser:\n%s\n", $authUrl); print 'Enter verification code: '; $authCode = trim(fgets(STDIN)); $accessToken = $this->client->fetchAccessTokenWithAuthCode($authCode); if(!file_exists(dirname($credentialsPath))) { mkdir(dirname($credentialsPath), 0700, true); } file_put_contents($credentialsPath, json_encode($accessToken)); printf("Credentials saved to %s\n", $credentialsPath); } $this->client->setAccessToken($accessToken); if ($this->client->isAccessTokenExpired()) { $this->client->fetchAccessTokenWithRefreshToken($this->client->getRefreshToken()); file_put_contents($credentialsPath, json_encode($this->client->getAccessToken())); } return $this->client; }

This is the request the I send:

public function replaceAllShapesWithImage(array $data_images) { $requests =array(); if(isset($data_images)){ foreach ($data_images as $key => $value) { $requests[] = new \Google_Service_Slides_Request(array( 'replaceAllShapesWithImage' => array( 'imageUrl' => $value['url'], 'replaceMethod' => $value['replaceMethod'], 'containsText' => array( 'text' => $value['text'] ) ) )); } } return $requests; }

$data_image has this value:

'replaceAllShapesWithImage' => array( 0 => array( 'text'=>'{{LOGO}}', 'url'=>'http://www.16cafe.com/wp-content/themes/16cafe/css/images/logo.png', 'replaceMethod'=>'CENTER_INSIDE' ), 1 => array( 'text'=>'{{PHOTO}}', 'url'=>'http://localhost:9880/wp-content/uploads/2017/02/pla23.jpg', 'replaceMethod'=>'CENTER_INSIDE' ), )

Every time I catch an API error my script waits 1 second. If the error occurs again the script waits 2 seconds. Then 4 seconds, 8 seconds, 16 seconds. In total I make 5 attempts. It works every time.

public function get_analytics_response() { $api_call_num_of_attempts = 5; $api_call_attempts = 0; $api_call_sleep = 1; do { try { $response = $this->analytics->reports->batchGet(); } catch (Google_Service_Exception $e) { // Sleep 1s, 2s, 4s, 8s, 16s + random milliseconds $sleep = ($api_call_sleep * 1000000) + rand(1000, 1000000); usleep($sleep); $api_call_attempts++; $api_call_sleep = $api_call_sleep * 2; $error_message_json = $e->getMessage(); $error_message = json_decode($error_message_json, true); // Save errors... continue; } break; } while ($api_call_attempts < $api_call_num_of_attempts); return $response; }

Slides can definitely give better error messaging, but I'm pretty sure the problem is that http://localhost:9880/wp-content/uploads/2017/02/pla23.jpg image URL you are trying to insert. I tried making a replaceAllShapesWithImage request with that image and also got a 503.

Slides downloads your images over the public internet, so a localhost domain wont work. Try hosting it on some publicly accessible URL, or you can use Google Drive to host the image.

I had the same error message (for a totally different reason).

For me, I waited 30 seconds and attempted the same thing again, and it worked.

Seems it may simply be a brief outage of the Google API.
