React version: Not related

The current behavior

We're following this to set up react-devtools.

If your app is inside an iframe, a Chrome extension, React Native, or in another unusual environment, try the standalone version instead. Chrome apps are currently not inspectable.

The standalone version works well, but if the standalone version is not started, react-devtools will try to connect ws://localhost:8097/ and prints too many logs.

The expected behavior

I hope react-devtools can only print 1 error message if it is not connected to the standalone version.
