Workspace created by compose recipe url does not start (regression)

[artaleks9]

When I try to create workspace by compose recipe url from stack import, then workspace does not start.

Reproduction Steps:

• Go to the 'Workspaces' -> 'Add workspace' -> 'Runtime' -> 'Stack import' on the dashbord.
• Select compose recipe type and enter recipe url (e.g. https://gist.githubusercontent.com/idexmai/6918415efa88276bdf028756adc8b9fb/raw/04ea419e25e02d010a03d75278606c3e2218e1e6/composeJavaStack)

Expected behavior:
workspace should be created.

Observed behavior:
workspace is not created and there is unexpected error.

@artaleks9 do you have server traces ?

[garagatyi]

It is because of NPE on server side
