eventually a question also for a custom resolver which can return errors / mock data if not available. we build an example here: gamedaoco/gamedao-haiku#441

[vovacha]

I guess it's still should be fixed in a fax and simple way and then wait for the mocks to be ready.

[vovacha]

Not reproducible. I am moving this issue to Done until it happens again.

[vovacha]

It happened again. Moving to the backlog.
