The example on Readme is not working with Inspector tool

[LRagji]

Exact example on the readme.md is not working the with mcp inspector it returns an error saying not reachable. 404
Inspector logs
`
New StreamableHttp connection request
Query parameters: {"url":"http://localhost:3015/mcp","transportType":"streamable-http"}
Created StreamableHttp server transport
Created StreamableHttp client transport
Client <-> Proxy sessionId: d36fc01f-91e1-4d4b-ac39-37cce8c63d2d
Error accessing endpoint (HTTP 404)

When i debug i can see the connection being received in express app and follow it till await transport.handleRequest(req, res, req.body);` post which nothing else happens.

Latest version of lib 1.20.x

When working with Koa, you'll need to add the following to your code:

// Tell Koa not to handle the response since we're using the native res object directly
ctx.respond = false;

This prevents Koa from automatically handling the response when you're working directly with Node's native response object.
