Nested asynchronous resolvers in a subscription

[art1415926535]

My subscription class have nested objects. The first level asynchronous resolver working perfectly. The second level breaks subscription request and not produce any response.

Ok:
{ async { sync } }

Breaks:
{ async { async } }

I created a test project with examples above:
