This can happen when you create a condition that accesses fields from different tables, without using the relationship between tables with dotwalk.
For example, you create a condition to check if the start date of a Change Task is greater than the start date of the corresponding Change for this task.
To solve it you need to define the condition object as "Change Task" and the fields would be "start_date" which refers to the Task itself and "chg.sched_start_date" which refers to the Parent Change.
Notice the use of "chg." to use the dotwalk and be able to access a Change field from the Task of this change.
Without this "chg." you may receive the error.
