I use this assistant for not only vaadin but also for everything. You said, the code needs to be updated to use Serverless index and this is what I got from Pinecone AI support. Hope this helps you to quickly fix the issue

        String region = "us-east-1";

        // Create index
        createServerlessIndex(apiKey, baseUrl, indexName, dimension, metric, cloud, region);

        // Query index
        float[] embedding = {/* Your embedding values */};
        int maxResults = 10;
