An error occurred when I use Timeline and NodeCanvas together

[fanParticipant]

If I define a “TimelineAsset” field in an action node and add the node to a graph,then an error occurred when I try to select the Timeline clip in Timeline editor window.

How can I fix the error?

The Unity version is 2022.2.0b8.

Hello,

There has been a hotfix regarding attributes in the latest version live on the Asset Store (it is the same version number however). Can you please try updating and let me know? Thank you!

Thanks.

I have updated to the newest version,but it doesn’t work.

It seems that the error is caused by deserialization.

Hello again and sorry for the late reply.

I just tried to replicate this with the latest version of NodeCanvas from asset store and Unity 2022.1.19f1, but there were no errors poping up. Just to clarify, here is what I tried:

1) I made a simple custom Action Task with a public Timeline Asset type field and added that action task in a graph.
2) I also assigned a Timeline Asset I had created there.
3) I opened up Unity’s Timeline Editor and selected various clips that I created within that Timeline.

Can you please let me know any way for reproducing the errors you see poping up?

Thank you.

Hello,

I replicated it with Unity 2022.1.19f1.Your steps are roughly right,but you missed something.

1.You need to bound the graph to a graph owner of game scene.

2.You need to trigger code recompilation,such as running the game scene.

If nothing else, you can reproduce this error.

Hello again,

I was able to replicate the error in the end and is indeed related to the previous attribute error. To fix this now, please open up ReflectionTools.cs and change the method named “RTGetAttribute” in line #893 to simply be like this:

1 2 3 4 5

public static Attribute RTGetAttribute(this Type type, Type attributeType, bool inherited) {             return type.GetCustomAttribute(attributeType, inherited);         }

Let me know if that works for you. Thanks.

[fanParticipant]

It works,thanks.
