UnityEditor.Graphs.Edge.WakeUp() having error

I don't even know what this error is coming from. I've never used UnityEditor.Graphs, nor do I know what it is. This error just randomly started appearing one day when I run my game. Double clicking the error takes me to a script I've never seen before.

 

Still no clue what's going on.

 

I'm having this error as well and no particular reason for this to occur. (2018.4.13)

 

Hi TreyK,

I have to say I'm kind of tired of doing bug reports. It takes time and so far, after a dozen of them, it never really helped in any way. I find a bug, I do a bug report, I upgrade to get the bug fixed, and there come 2 new bugs. I do 2 bug reports, so on and so forth... If I had nothing else to do, I'd do it, but I'm currently trying to work on game.

I think you guys should stop implementing new stuff, and fix all the bugs until it's clean. Pilling up new features on such a mess will never work.

You don't need more bug report, you already have a ton of projects to test. Open one project in Unity 5, open the same one in Unity 2019.2, and see for yourself.

Someone did something that you should have done a long time ago:

I am having the same issue all of the sudden in a project I am working on. Likewise, I've never used UnityEditor.Graphs, nor do I know what it is.

same issue with me...

blahblah...

Solution: RESTART!!

 

Worked.

 

Same here

 

RESTART its warked

 

RESTART is working just great!

 

restart has solved my problem

 

ANjay slurr cuma restart doang,, gua stack seharian cuma gara gara ini

welldone

 

Restart works thx.

 

Restarting would work for me, for a bit... The problem would inevitably re-appear within a few minutes of restarting though. I closed the Animator and Animation windows and restarted, and have not seen the problem appear again. Yet.

[Added Dec 16] This problem will still eventually recur any time I spend a significant amount of time animating. It's now just one of those things: "Oh, I've had the Animator and Animation windows open for too long, and Unity is too busted to handle that. Better close them and restart Unity".

 

This error happens out of your hand. Its pointing the source code object and nothing todo with it in unity. JUST RESTART! the unity and it will fix when turning on.

ps: possibly, when you are back to your project last job you did will be broken. since unity will recover the last working version of your project.

cheers.

 

IT works!!! As always.

 

So that bug report was pointless since it still hasn't been fixed, just got it now

 

I got the same issue when replacing a class (component on the game object) with an inherited class instead.

Restarting the editor made the problem go away. Annoying but not game-breaking.

 

Same problem . I think it is related to the animator/animation.

Code (CSharp):

I got this error after adding a struct that is visible in the editor to a scripted behaviour. Quitting and relaunching Unity solved it.

 

How to RESTART Unity Editor

 

Kould you help me please

 

Restarting the editor works for like 10 minutes or so then I get the error again, can anyone please help?

 

Yeah, restarting fixes the issue for a short while. However, I would like to see a fix from Unity so the problem doesn't exist. This bug seems to be related to Animator/Animation. This bug isn't game breaking in any way, just a little annoying to see a red message in console, so might be a low priority bug.

 

Exit and reopen it.

 

I also had this error since 5 days. No matter how many times I started Unity, the error came back after 10 minutes at the latest.

I then noticed that in the last 5 days, I had created many new scripts and these scripts were almost all "public static instance". In the further programming, I had accidentally, between

"public static <scriptname> instance" and "void Awake" => "instance = this;"

in some scripts I had created new bools and floats and put them in between. Finally, I moved the newly created bools and floats under the Awake method in all scripts, from that moment on, I no longer had this error. Maybe it helps one or the other.

 

restarting and having it reoccur isnt a solution. especially years later. i cant find a proper fix.

 

just restart

 

Yes, It's totally USEFUL!

 

This error still pops up. Pretty annoying.

 

Like the previous posts suggested, surprisingly, restarting the editor (2019.4.31f1) made the error disappear.
As a side note, I had the Animator and animation tab opened but not visible when I had this error.

 

im juts burn my computer and change another computer , ITS WORK

 

Still happening on 2022.3.22

 

Yup still happening to me as well.
