Behavior Tree Root script shows a red "Null (Assign)" in the Source property

[KontosTwo]

Here is what it looks like:

Here is the relevant manifest.json sections

Attempting to Play prints the following error log

What did I do wrong?

[KontosTwo]

If it helps, I also suffered from #157 but I made the errors go away by commenting out certain lines.

[KontosTwo]

It appears you have already fixed this in shtif's dependency according to pshtif/GenericMenuPopup#2 . You might have to update EntitiesBT's dependencies to use shtif's fixed version

[KontosTwo]

It's still red, but upon clicking the red field, I can select "GameObject" or "TextAsset". Looks like your fix worked - please update the Shtif package whenever you have the time

[quabug]

I am planing to fix this on next major version 1.4.0.
But you're right, I should also fix this on current stable.

[quabug]

Please update essential package to 1.3.1.
Feel free to reopen this issue if it still exist, thanks.
