Original GitHub issue: https://github.com/cloudflare/vinext/issues/1044

https://hyperdrive-test-dbt.pages.dev/api/test-hyperdrive

error: {"success":false,"error":"Uncaught TypeError: Failed to establish the WebSocket connection: expected server to reply with HTTP status code 101 (switching protocols), but received 530 instead."}

I can connect to the database normally, but I can't connect via Hyperdrive. How should I fix this?

code:

import { Client } from "pg";

export default {
async fetch(request, env, ctx) {
// Hyperdrive provides a unique generated connection string to connect to
// your database via Hyperdrive that can be used with your existing tools
const client = new Client({ connectionString: env.HYPERDRIVE.connectionString });
await client.connect();

try {
  // Sample SQL query
  const result = await client.query("SELECT * FROM pg_tables");

  return Response.json({result: result.rows});
} catch (e) {
  return Response.json({ error: e instanceof Error ? e.message : e }, { status: 500 });
}

},
}

Please can you share a repository that reproduces the issue?

I deployed a project last week that uses Planetscale Postgres via Hyperdrive and have not run into this problem.
