root ERROR Cannot find a service for the path: /services/glsp/WorkflowNotation/:id

I am developing glsp application, i am getting the above error when I try to launch the application. If I try restarting the server multiple times, it works without any problem. Any ideas on what could be the problem?.( I have modified the existing coffee editor example, so the contribution id is "WorkflowNotation" ). Is it related to backend or frontend. When I try debug the front end code, it is failing at websocket connection.

This looks like #558.
Strange however that it works when restarting multiple times. Could be a timing issue that the server takes a long time to come up? Does it also work if you start the server, wait a bit and then refresh the browser (even multiple times)?

Is there any notable difference between your code and the workflow example's Theia integration.

Theia integration example and coffee editor example have little difference. But I am able to reproduce the same issue in the coffee editor also.
One change I did on the coffee editor was, removed all generator, DSL and Analyser extensions and kept only GLSP extension. Also did not modify the background at all.

Hi, I tried to build and run the coffee editor example. I too encountered with the same error(Cannot find a service for the path: /services/glsp/WorkflowNotation/:id) Please look at the screenshot. Please let me know if someone finds root cause or solution. Thanks!!

Note: I didn't modify or touch the coffee editor code.
