Plugin not compatible with mongoose v9

[serolgames]

Hello,

I've updated my mongoose package to v9.
And now when I open my admin page I can login successfully but then I have the following error :

error <ref *1> ResourceDecorator {
...all my models definitions

TypeError: Cannot destructure property 'instance' of 'this.mongoosePath.caster' as it is undefined.
