inspector Unexpected token {

[xingyunyang01]

My demo is currently working and has been tested on claude Desktop. But when I try to use inspector, it reports an error, screenshot below：

I used the official mcp-server-sqlite code to test it and it doesn't work either

What is the reason for this? Thank you.

Can you check the content of the json file that was written by mcp dev?

It's my node version that's too low, just upgrade it to the latest version.
