Error js imagen 3 generation

[tronycoder]

Hello, 

Trying to Run this code:

const project = 'PPPPPPPPP';  
const location = 'us-central1';

// Import the Vertex AI library
const {PredictionServiceClient} = require('@google-cloud/aiplatform').v1;

// Set up the client
const client = new PredictionServiceClient();

async function generateImage() {

// Full endpoint for the model
const endpoint = `projects/${project}/locations/${location}/publishers/google/models/imagen-3.0-generate-001`;

// Create the request with the prompt
const request = {
endpoint: endpoint,
   instances: [
         {prompt: 'A futuristic cityscape at sunset'}
    ]
};

// Call the API to generate an image
try {
   const [response] = await client.predict(request);
    console.log('Generated Image:', response.predictions);
} catch (error) {
     console.error('Error generating image:', error);
}

}

generateImage();

===

I get the error:

Error generating image: Error: 12 UNIMPLEMENTED: Received HTTP status code 404
