Call to undefined method Laravel\Nova\ResourceToolElement::fill()

[Luke]

When adding inline morph to User, all resources can be created as intended (eg Teachers/Admins) except for Students.

 InlineMorphTo::make('Userable')
                ->types( [
                        Individual::class,
                        Student::class,
                        Teacher::class,
                        SchoolAdmin::class,
                        Admin::class,
                    ])
                ->default(Student::class)->hideFromIndex()->hideFromDetail(),
