eclipse-emfcloud/modelserver-glsp-integration upgrade to 2.2.1 issue

[amiths89]

I am trying to run this project (eclipse-emfcloud/modelserver-glsp-integration) but it looks there is an issue, i was seeing the same issue as eclipse-emfcloud/modelserver-glsp-integration#58 here so i decided to upgrade it to glsp 2.2.1 for which i updated the typescript code for this. And i was able to start the application but i get the below error in the tasklist-diagram which could be due to not updating glsp-server and model-server to 2.2.1 which am not really sure how. Would there be an easy fix for this or atleast an updated version of this project with glsp 2.2.1

edit:
Also One of the issue I am facing with this modelserverintegration code is that the default format is json-v2 whereas the example.tasklist is based on XML format. So my assumption is that maybe I need to update the frontendendmodule to change the format to XML instead of json-v2. Although again am not sure how to do this, would that fix the issue here eclipse-emfcloud/modelserver-glsp-integration#58

or it could be an issue with the encoding of the URL as I am able to GET the resource in browser with the correct URL but in stack trace I see an encoded URL with status 404 error. If this is a double encoding issue, Can you show me where this can be fixed?

This comment #214 (comment) fixed the double encoding error I had in the URL and thereby resolved the resource issue I faced.
