Incompatible SockJS! Main site uses: "1.4.0", the iframe: "1.3.0".

Hi there,

I just upgraded to react-scripts v3.2.0 and am now see the below error in the console in my dev server:

Seems the issue is coming from the sockjs-client package. Tracking it down in my package-lock, react-scripts requires webpack-dev-server which in turn requires sockjs-client v1.3.0. react-scripts also requires react-dev-utils, which requires sockjs-client v1.4.0. I think that's where the mismatch is coming from.

Do you have any advice moving forward?

Thank you.
