Debugger trying to use SSE even when set to STDIO

[matteematt]

My setup

1. I have created a new project using mcp create project-name
2. I have added a new tool uisng mcp add tool tool-name
3. I have run npm run build so there are js files in /dist
4. I have run npx @modelcontextprotocol/inspector dist/index.js and opened the debugger on in my browser

On the browser my config is STDIO and dist/index.js

But when I click connect I receive

New SSE connection

It looks to me like the error is that it's trying to use sse to connect to the debugger and failing as I didn't add any SSE config. But I don't think I should need to use SSE because of selecting STDIO. Also I don't want to add SSE consiering it's deprecated
