Hello everyone ! First of all thanks for reading this message and trying to contribute ! :grinning:

Context: I’m currently trying to create a custom blueprint node using the Kismet Uk2Node class. All my code is in a plugin submodule which is of type UncoockedOnly with the loading phase set to PostDefault.

My node has an input pin of type FGameplayTag declared like this :

LogProfilePin = CreatePin(EGPD_Input, UEdGraphSchema_K2::PC_Struct, GetLogProfilePinName());
	LogProfilePin->PinToolTip = LOCTEXT("LogProfilePinToolTip", "The log profile to use for this log node.").ToString();
	LogProfilePin->PinType.PinSubCategoryObject = FGameplayTag::StaticStruct();
	LogProfilePin->PinType.bIsReference = false;
	LogProfilePin->PinType.bIsConst = true;
	LogProfilePin->DefaultValue = FGameplayTag::EmptyTag.ToString();

When the tag change i need to fetch the new value of the pin to search an object in porject’s settings. To do so i need to get the Pin value as string (because kismet work like that) and then i try to convert it as a FGameplayTag using :


FGameplayTag LogProfileTag = FGameplayTag::RequestGameplayTag(FName(*ProfilePin->DefaultValue));

But here is the problem…

Problem: When the tag change my callbacks run the code shown above ant it run into this error :

I’m very confused because my tags are valid and loaded in the editor (i can see and manage them in settings + I can select them in the pin GameplayTag selector). I also tried to replace all my GameplayTag with native tag but same problem occur.

More confusing information is that when i run my game, the node execution is perfect and use the tag with no error at all (not even a warning!).

I write this post after two day of debugging and today I’m asking for help because i have no more idea to fix this.

Thanks again for reading and/or helping :grin:

I finally found the problem and it was right in front of me all the time…

The problem was that the string i used to request the GameplayTag was not formatted.
I used “TagName=“BULogProfiles.Default”” instead of just “BULogProfiles.Default” so that’s why the GameplayTagManager can’t find it… I feel a little bit dumb but I’m happy that my bug is now fixed ! :star_struck:
