Hey there, exactly the same happens for me. When I try to make a Dolly Camera with Track, I can't seem to record.


With which Unity version? Also, what is the Timeline package version (you can get that information in the Package Manager window).

Unity 2019.2.9f1
Unity Timeline 1.1.0

Any more info on this? I got this on 2019.2.18f1 today with Timeline 1.1.0. First time trying out timeline so a little at a loss at where to go from here.

A simple restart of Unity seemed to fix it for now for me.

The error seems to be related to your current layout. As a workaround, if it happens again, try reverting your current layout.

Resetting the layout works for a while, but the error resumes some arbitrary time later. We cant isolate it to a particular window being open or not.

This issue still exists in 2019.4.13f1 and Timeline package v1.2.17. I was able to resolve by resetting the editor layout.

This is a known issue - as of right now, the issue is currently marked as won't fix. Resetting the layout is the recommend workaround - we have had a difficult time getting a consistent repro project.

If resetting the layout does not fix the issue, please submit a repro project so we can reopen the issue and deliver a fix.


Worked for me too, thanks a lot, I never would've guessed that!

Resetting layout worked for me. i have been looking around everywhere, but now it works

How is that bug marked as won't fix ?
Resetting the layout works temporary, the bug come back after some time.

As stated above, we have not been able to reproduce the issue. If you have a repro case, (including layout files) please submit them.

Small update on this. Literally - a couple hours after posting 2 separate people at Unity starting experiencing this. So, we have a valid repro case and have reopened the bug.

With luck we will have a fix soon.

Still happening in Unity 2019.4.14.f1 (LTS as of today). Any fix yet?

The fix will be available in 2019.4.15f1.

Can confirm setting your layout to default fixes the problem
