Symptoms
- I am getting the error below appearing in my console:
NullReferenceException: Object reference not set to an instance of an
object
Cause
This error is caused when an object is trying to be used by a script but does not refer to an instance of an object.
Resolution
To fix this example we can acquire a reference to an instance of the script using GameObject.Find to find the object it is attached to. We then use GetComponent to find the script component we want a reference to.
You can also double click the error to take you to the line of script where the error is occurring.
From there you can trace each object back to where they are assigned (if they have been assigned).

Great.... Thanks!
Hello, i've got the same issue but i don't want to put a "Find" function with a name. So i can use it with multiple objects.
Is it possible with "this" ? I tried but i still get the error at myOutline.enabled=false;
Thank you!
In case anyone attempts this and it STILL doesn't work, let me recommend what worked for me.
I was attempting to get an initiative value out of a Timeline script on my Units in a turn-based tactics game.
But the Timeline is not directly ON the Unit, but on the initiative button that will be moving along the timeline UI element. It's down in Unit > Canvas > InitButton.
For a situation like this, where you're setting up complex objects like a file structure, you can dig in to the specific script using GetComponentInChildren. The regular GetComponent won't find your script, because it's not directly on that containing "folder" object.
Thanks NO HATE
I looked up this error and got here... but that is literally how my code is already written as.
GameObject.FindGameObjectWithTag("RedCube").GetComponent<Renderer>().enabled = false;
@Jeremy thanks dude, it's a super dumb "error" but it was the error. For some reason if you test the game in preview it works without "InChildren" but when built it was needed and i was keep getting the error without knowing what could it be. And it was that... It would be good if Unity adverts or something about it.
This saved my life.
Bolt no longer works in any way not even in a new project. I've uninstalled unity bolt and reinstalled and everything. It still comes up with fixing compiling errors?
This error also arises when you have used the script somewhere in game, but forgot to add it to a gameObject which is using it. So for example in my case I was working with a shooter game in which the fire projectile object was using the script but i forgot to add it. SO YES check it out for your game.
O Thank You So Much Sir. It Worked For Me. I was getting this error from long time but now after trying your solution it really worked. Oh Yeah
Thank you! I didn't realize you could just double click the error message to take you to the line of code that was the issue.
Thank You so much Sir
Thank you bro!
Had this problem... had. Turns out the save was just corrupted. There goes multiple hours of my life trying to fix what was not broken.
Hi there,
You can try moving GetComponent from Start() function to Awake() function.
It worked for me in case of this Error.
how do i fix this in bolt tell me or give me a link or something i have spent hours just trying to figure this out i am new to unity and it is stressing me out
