Blueprint error

When I start my game I get the following errors

Blueprint Runtime Error: “Accessed None trying to read property CallFunc_GetParentActor_ReturnValue_1”. Node: Branch Graph: IsValid Function: Execute Ubergraph BP Interaction Area Master Blueprint: BP_InteractionArea_Master

Blueprint Runtime Error: “Accessed None trying to read property CallFunc_GetParentActor_ReturnValue_2”. Node: Set InteractWidgetComponentRef Graph: EventGraph Function: Execute Ubergraph BP Interaction Area Master Blueprint: BP_InteractionArea_Master

Can you help me solve these errors

Show us the script that triggered it. Either the references are invalid or the actor instances do not exist when accessed.

I’m sorry, I didn’t understand exactly what you wanted from me.

Find the place in your script that triggers the errors, show us screenshots of the offending pieces and explain what you were doing. Also do tell what the general goal is and what you want to achieve.

Those errors generate messages in the log, you can click on them and it will take you to the part of the script that failed.


What you posted only tells us you have invalid references. Too little to advise anything.

When I click on the error it takes me here.
When an object enters a certain collision area, I want it to focus on the object, create a yellow stripe around it, and then interact with it. For example, the light turns on when you press the “E” key.

This script you posted does not seem to be related to this. Perhaps you could follow along a tutorial:

This is a feature that has been explored quite extensively.


When it comes to the errors:

There can be multiple issues:

  • no parent actor
  • no component on parent actor
  • wrong tag

Going by the script I do not understand what you’re trying to do. Normally, it would be the player / controller who would interact with a widget providing we’re inside an interactive area.

Here it seems that it is the area that is trying to fetch a widget? Even if you did manage that, what would be the next step.

Actually, I did this by looking at a tutorial video series. All my steps were correct, but when I did the steps in the last video of the series, all my codes were broken.
