Expected behavior:
The server is launched and listen for a defined port.
Observed behavior:
Server launch failed because of unexposed port
OS and version:
Che 7.0.0-beta-5.0-SNAPSHOT
Attachment:

If change "editor" to "eclipse/che-theia/next" in the workspace config, the node server launch works as expected. Thank @sunix for help.

@Ohrimenko1988 Now next should be default version https://github.com/eclipse/che/pull/13235.
Should this issue be closed?
In my opinion, it may be closed.
