I’ve seen others with this type of error using the engine, but I’m making a plugin and am testing functionality for adding member variables to blueprints via a separate widget, and every time I do it if I try to compile the blueprint it will throw me these errors:

LogBlueprint: Error: [Compiler Test] Internal compiler error inside CreateExecutionSchedule (site 1); there is an issue with node/pin manipulation that was performed in this graph, please contact the Blueprints team!

LogBlueprint: Error: [Compiler Test] The property associated with Delta Seconds could not be found

LogBlueprint: Error: [Compiler Test] ICE SetVariableOnPersistentFrame - No property found. Delta Seconds

It seems to be an issue with a “Tick” property, here is a picture of the tick after the error is thrown, but I’m not sure what is out of place because I haven’t seen the Tick before the error is thrown.

The thing that bothers me the most is that the process that I used to create new member variables is basically copied from the “DoPromoteToVariable()” function in BlueprintEditor.cpp (which works fine) so I’m not sure what I’m doing to cause this error. I’m not really sure where to go from here, maybe I should use a newer version of UE4? Either way, I would appreciate some advice.

Thanks for any help!

Your graph is a little hard to read since you arranged the Tick node backwards. Also I am confused why it is purple. Did you override the original tick with your own function?enter code here

This is how graph looks if you click on links in the compiler result.

I didn’t have this issue before, but in UE 5.1 it was already twice. What I did was copy the Collapsed Graph from one Blueprint to another.
