Can anyone help with this error code?

I keep getting the same error code while playing and it's super annoying bc it blocks my screen when I get multiple of it. Here's the code:

[Scripting] [error] - TypeError: cannot read property 'container' of undefined at <anonymous> (unlinked/unlinked.essentials.js:3608)

I wonder if it's from the add-ons i'm using but i could be wrong.
