Call to a member function get() on null

[MazzMazz]

Specs:
Laravel 7.x
Nova 3.x

Problems

When upgrading the Plugin to Version 1.1.x we get the following Exception.
We downgraded again to 1.0.11 with which everything works as expected.

{
    "message": "Call to a member function get() on null",
    "exception": "Error",
    "file": "{{pathToProject}}/vendor/dillingham/nova-attach-many/src/Http/Controllers/AttachController.php",
    "line": 46,
    "trace": [
        {
            "file": "{{pathToProject}}/vendor/dillingham/nova-attach-many/src/Http/Controllers/AttachController.php",
            "line": 30,
            "function": "getAvailableResources",
            "class": "NovaAttachMany\\Http\\Controllers\\AttachController",
            "type": "->"
        },
        {
            "file": "{{pathToProject}}/vendor/laravel/framework/src/Illuminate/Routing/Controller.php",
            "line": 54,
            "function": "edit",
            "class": "NovaAttachMany\\Http\\Controllers\\AttachController",
            "type": "->"
        },
        {
            "file": "{{pathToProject}}/vendor/laravel/framework/src/Illuminate/Routing/ControllerDispatcher.php",
            "line": 45,
            "function": "callAction",
            "class": "Illuminate\\Routing\\Controller",
            "type": "->"
        },

This happens in Version 1.1.1 and 1.1.0

Nova Resource Part

AttachMany::make(Tag::$singularLabel, 'tags', Tag::class)
                ->fullWidth()
                ->showPreview()
                ->height('200px')
                ->help('A Hint for the user.')
                ->showCounts()
                ->hideFromIndex(),

Eloquent Relation Part

public function tags(): BelongsToMany
    {
        return $this->belongsToMany(
            Tag::class,
            'b2b_product_tag_mapping',
            'product_id',
            'tag_id')->withTimestamps();
    }

Did you ever find a solution to this except for downgrading?

I think I'll have another look on this

Used this Plugin(1.1.1) in another Projekt (Laravel 8.26.1, Nova 3.21.0) and everything works fine.

However i just tried again (in the Projekt with the Problem) and even though the Laravel and Nova Versions are the same i get the mentioned error. The implementation in the Resource looks the same.

@MazzMazz hmmm wonder why this line is returning null for you

[adamiatro]

@dillingham Please let me know if you'd rather I open a separate issue for this.

In my implementation, AttachMany works for one model (Users) but not for another in the same resource.

AttachMany::make('Users'),
BelongsToMany::make('Users'),
BelongsToMany::make('Organisations'),

This works.

AttachMany::make('Users'),
BelongsToMany::make('Users'),
AttachMany::make('Organisations'),
BelongsToMany::make('Organisations'),

This only works partially, as the Users model works fine but the next one returns null.
