Resolution:
Correct the code to place the AWAIT expression within an ASYNC method.
Example:
The following example shows an AWAIT expression used incorrectly outside of an ASYNC method:
$set ilusing"System"
$set ilusing "System.Threading.Tasks"
$set sourceformat(variable)
class-id A.
method-id Main static.
invoke await type Task::Delay(1000);
end method.
end class.
