Code
T4005 async-run
The run of a query or of a change is written async. Both answer at once: a query reads through db, and the whole of a change is one write, which cannot wait for anything outside.
Details
It is also found for an async arrow that is handed to each in a query, in a change or in the arrow of a rule, where nothing may be waited for. The type checker refuses the same run, as code.T8000.
The fix
Take async away. What must be waited for belongs in an action, which calls the query or the change.
