Cannot launch the glsp-examples

[dinkoivanov-gepard]

Hi,

I'm trying to run the node-json-vscode example by following the readme https://github.com/eclipse-glsp/glsp-examples/blob/master/README.md.
I manage to build the project with yarn, but when I try to run it, the server starts ok:

4:57:13 PM info -  [SocketServerLauncher] The GLSP server is ready to accept new client requests on port: 5007 
[GLSP-Server]:Startup completed

But the client reports an error:

[JsonrpcGLSPClient] Connection to server is erroring. Shutting down server. (1) [Error: connect ECONNREFUSED 127.0.0.1:5007
	at TCPConnectWrap.afterConnect [as oncomplete] (node:ne…]

Please help,
Thanks,

@dinkoivanov-gepard I have the same issue on macOS and other also on windows. Using a linux machine or a container should work. I'm using the dev container of the node-json-theia and it works.

Thanks for raising this issue. Others have observed this recently as well and a bug has been raised: #1100

We didn't get to investigate this yet further, but certainly plan to look into at soon, as it seems to affect many people. If you have any further insights or possibly a fix already, please feel free to share your findings! Thank you!
