The problem with custom inspectors, is that custom inspectors code is very tied with the serialization that is used behind the scenes.
Unity, Odin and NodeCanvas, all three use different serialization and this is why inspectors made using the API for one of those, do not work with inspectors made for the other. Just in case you do not know, you can create custom inspectors in NodeCanvas for any type, but of course these inspectors are only made to inspect types within NodeCanvas (variables and nodes inspection).
