After Effects error: internal verification failure, sorry! Item must be a comp // 5027::91

Hi there,

I have a problem with my After Effects project. Whenever I move forward or back in the timeline, this error message comes up. I can not work properly on the file anymore, but I urgently need to export some plexus effects as SVGs and work in it.

Can someone help me how to fix the mistake?

Regards Stephan

my bad.. it's all good now.. I forgot to remove Auto Crop from Media Core as well (I previously removed it just from the SriptsUI Panels folder.. so Auto Crop was the faulty plugin after all.. when completely removed, everything works fine and the error is gone.. thanks a lot for your time!


just an update: it looks like the author of that script / plugin was aware of the problem, 'cause I see they fixed it in the most recent update: "Fix error when a non-composition is selected in the project panel" (quote from plugin's version history).. so probably not much you can do within After Effects' code about this error

If you’re still experiencing these issues, the next plugin to check and remove or update is (UnPrecompose).

This worked for me.

Removing “UnPrecompose” Plugin fixed the issue for me. Thank you!

Hi, for me this exact issue was arising because of the plugin called AutoCrop.
Removed the plugin file from the Support files, and this issue got fixed.

for me it was a plugin called "UnPrecompose", updated the plugin to the latest version and everything back to normal

Just delete the effect which u have used in your last auto save and save the file with a new name it will help.

I'm actually having the same problem... whether I create a new project or open an existing one.. most of the times, when I want to delete a folder or a comp or a solid or whatever, I get the same error... sometimes, when I want to click on a menu item, I get that error (not allowing me to open that menu)... if I scrub through the timeline, then click on a menu again, no more error... but it pops up again (apparently randomly) when I want to delete any item from the project panel... I installed a few extensions and scripts lately, did some troubleshooting removing them one by one, I still get the error... I deleted all my preferences, I uninstalled then reinstalled After Effects (keeping my scripts and plugins, though) and I still get the error

In your Help menu (inside After Effects), can you see an Enable Logging option? If you turn that on and then reproduce the error, there should be a log file written out to disk which you can find from the same Help menu -> Reveal Logging File. That might contain some info that can help us diagnose the issue.

https://www.dropbox.com/s/ctesuf1djsiney2/After%20Effects%20Log.txt?dl=0

that's the error log..

I started a new project, created 2 new comps, 2 new folders, moved one comp inside a folder then tried to delete the folder and I got the error

I clicked ok on the error, tried to open a menu, got the error again

the error text, inside that log file, is: U U_Sev_PROBLEM After Effects error: internal verification failure, sorry! {Item must be a comp}    ( 5027 :: 91 )

I can't make much of the info in the log file, unfortunately

Can you post the AEP project somewhere that we can download it so we can see what the issue is?

Thanks

It's not actually any particular project but just it wouldn't let me handle any kind of file in the project panel without this window popping:

Any time I would right click or do any action to any file other than just left click, that would happen.

Why is that?

So every project you open or any new project you create?

Can it possibly be a conversion problem? I use a MacPro and have AE CC 2018, the latest version.

Install CC2017.  You can have multiple versions on your machine.
