Create action with relation throws error

Sorry for the vague title I have the following action

Actions\Action::make('createUser')
  ->form([
    TextInput::make('email'),
    Select::make('roles')
        ->multiple()
        ->searchable(false)
        ->preload()
        ->options(Roles::options()) // This is an enum
        ->getOptionLabelFromRecordUsing(fn (Role $record) => Roles::from($record->name)->getLabel())
        ->relationship('roles', 'name'),
  ])
  
  ->action(function ($record, array $data) {
      $record->user()->create($data);
  })

Actions\Action::make('createUser')
  ->form([
    TextInput::make('email'),
    Select::make('roles')
        ->multiple()
        ->searchable(false)
        ->preload()
        ->options(Roles::options()) // This is an enum
        ->getOptionLabelFromRecordUsing(fn (Role $record) => Roles::from($record->name)->getLabel())
        ->relationship('roles', 'name'),
  ])
  
  ->action(function ($record, array $data) {
      $record->user()->create($data);
  })

When I click on the button, I get the following error

Filament\Support\Services\RelationshipJoiner::prepareQueryForNoConstraints(): Argument #1 ($relationship) must be of type Illuminate\Database\Eloquent\Relations\Relation, null given, called in /var/www/.../vendor/filament/forms/src/Components/Select.php on line 765

This is the exact same form I use in the UserResource and it works when creating a new user, but for some reason doesn't work when doing it outside the resource. I tried adding

->model(User::class)

->model(User::class)

and some other things but nothing worked. What am I doing wrong?

Solution:

Yeap, everything is setup correctly. The form works when used in the UserResource but since I was trying to create the user object from another resource, it would get messed up. Here's the final solution that worked for me ```php Actions\CreateAction::make('createLoginDetails') ->label(__('Create login details')) ->hidden(fn () => $this->getRecord()->user !== null)...

Seems to me that the relationship roles does not exist in your model, are you sure that's the correct name?

Actions\CreateAction::make('createLoginDetails')
    ->label(__('Create login details'))
    ->hidden(fn () => $this->getRecord()->user !== null)
    ->form(UserResource::getFormFields()->all()) // This gets me the form to create a user
    ->model(User::class)
    ->fillForm(fn () => [
        'name'  => $this->getRecord()->name,
        'email' => $this->getRecord()->email,
    ])
    ->mutateFormDataUsing(function (array $data) {
        $data['contact_id'] = $this->getRecord()->id;

        return $data;
    }),

Actions\CreateAction::make('createLoginDetails')
    ->label(__('Create login details'))
    ->hidden(fn () => $this->getRecord()->user !== null)
    ->form(UserResource::getFormFields()->all()) // This gets me the form to create a user
    ->model(User::class)
    ->fillForm(fn () => [
        'name'  => $this->getRecord()->name,
        'email' => $this->getRecord()->email,
    ])
    ->mutateFormDataUsing(function (array $data) {
        $data['contact_id'] = $this->getRecord()->id;

        return $data;
    }),

Essentially, I have a contact record that is linked to a User - users are only used for authentication purposes
