Google Cloud Vertex AI: CONSUMER_INVALID 403 error in WordPress for text summarization

In My WordPress, I am creating a text summarization function using the below function:

function call_vertex_ai($text_to_summarize) {

    // Get the access token using the service account
    $serviceAccountFile = (PLUGIN_PATH . 'vertex_sa.json');
    $accessToken = getAccessToken($serviceAccountFile);

    // Google Cloud project details
    $project = 'my-posts-data-optimization';
    $location = 'us-central1';
    $publisher = 'google';
    $model = 'gemini-1.5-flash-002';

    // Prepare the API endpoint and payload
    $endpoint = "https://us-central1-aiplatform.googleapis.com/v1/projects/'.$project.'/locations/'.$location.'/publishers/'.$publisher.'/models/'.$model.':predict";

    $requestBody = [
        "instances" => [
            ["content" => $text_to_summarize]
        ],
        "parameters" => [
            "temperature" => 0.7,
            "maxOutputTokens" => 100, // Ensure a 100-word limit or equivalent in tokens
            "topP" => 0.8,
            "topK" => 40
        ]
    ];

    // Make the cURL request to the Gemini model
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $endpoint);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
    curl_setopt($ch, CURLOPT_HTTPHEADER, [
        "Authorization: Bearer $accessToken",
        "Content-Type: application/json"
    ]);
    curl_setopt($ch, CURLOPT_POST, true);
    curl_setopt($ch, CURLOPT_POSTFIELDS, json_encode($requestBody));

    $response = curl_exec($ch);
    $httpCode = curl_getinfo($ch, CURLINFO_HTTP_CODE);
    curl_close($ch);

    if ($httpCode == 200) {
        $responseBody = json_decode($response, true);
        return $responseBody['predictions'][0]['content']; // Return the summarized text
    } else {
        error_log("Error with the request. HTTP Code: $httpCode");
        return "Error: Unable to summarize text.";
    }
}

In IAM, principal [email protected] has been assigned AI Platform Admin & Vertex AI user roles.

What's working are:

$serviceAccountFile path is correct, and the credentials in the file are valid.

$accessToken returns a valid token.

$text_to_summarize is passed to this function from another function and has valid content.

I am getting the following 403 errors:

"message": "Permission denied on resource project '.my-posts-data-optimization.'.",

"status": "PERMISSION_DENIED",

"reason": "CONSUMER_INVALID",

What could be the potential mistakes I need to correct to make this function work?

After debugging, I found how I constructed the $endpoint with variables is troubling. Not the permission issues.

Below is the correct one without single quotes:

$endpoint = "https://us-central1-aiplatform.googleapis.com/v1/projects/$project/locations/$location/publishers/$publisher/models/$model:predict";
