9 FAILED_PRECONDITION: dimensions is required but missing from Index metadata.

[pbiasotti]

I'm trying to create an index using the NodeJS sdk but I'm getting the following error. Initially i was trying to create it using a json file uploaded to cloud storage seting the uri in contentsDeltaUri but same happens when I try to create it empty. What am I doing wrong?

This is the smaller snippet to replicate the error

async function main(
    project = 'PROYECT_NAME',
    apiEndpoint = 'us-central1-aiplatform.googleapis.com',
  ) {
    const aiplatform = require('@google-cloud/aiplatform');
    const {IndexServiceClient} = aiplatform.v1;
    const clientOptions = {apiEndpoint: apiEndpoint};
    const location = 'us-central1';

    async function createIndex(indexName, embeddings) {
      const indexClient = new IndexServiceClient(clientOptions);
      const parent = `projects/${project}/locations/${location}`;
  
      const index = {
        displayName: indexName,
        description: 'An index created for storing embeddings',
        metadata: {
          config: {
            dimensions: embeddings[0].embedding.length,
            approximateNeighborsCount: 1000,
            distanceMeasureType: 'DOT_PRODUCT_DISTANCE'
          }
        }
      };
  
      const request = {
        parent,
        index
      };
      const [operation] = await indexClient.createIndex(request);
      const [response] = await operation.promise();
      console.log('Index created successfully:', response.name);
      return response.name;
    }

    const indexName = 'test-index';

    // this is just an example but is not used (only for setting the dimensions of the index)
    const embeddings = [
        { id: "0", embedding: [0.027309643104672432, -0.0033781714737415314, 0.011493228375911713] },
        { id: "1", embedding: [0.01877667009830475, -0.07062038034200668, -0.044831905514001846] },
        { id: "2", embedding: [0.034117065370082855, -0.01877667009830475, -0.07062038034200668] }
      ];

    console.log(`Creating index "${indexName}" ...`);
    const indexId = await createIndex(indexName, embeddings);
    console.log('Created index with ID:', indexId);

  }
  
  main()
