In subtasks, when error in chained tasks pass "No Answer" instead of the error

[MrtinoRG]

@aaaghajani reported that it is not ideal that in the subtasks or chained tasks, when there was some error in the subtasks run, if there is another subtasks that depend on this failed one, those inputs should not contain the error but perhaps something like No Answer.

Perhaps No Answer it is not descriptive enough as there might be tasks that do not have answer. Ideally it should be a fixed message as Error while running task
