I have a simple process builder on opportunity product (on create&edit) to pull value of related Products Family on to a text field (Product_Family_For_Backend_Use) on opportunity product. The process builder was working fine but sometimes its showing error :
Error element myDecision (FlowDecision). Formula result is data type (Object), incompatible with expected data type (Text).
