$container must not be accessed before initialization from within Action

I have the following header Action on an EditOrder resource page.

Actions\Action::make('process_return')
    ->form(function(Get $get, $record) {
        $fields = [];

        foreach ($record->items as $orderItem) {
            $fields[] = Group::make([
                Placeholder::make($orderItem->id.'product_title')
                    ->label('Product')
                    ->content(function() use ($orderItem) {
                        return $orderItem->product_title . ($orderItem->product_option_title ? ' - ' . $orderItem->product_option_title : '');
                    }),
                TextInput::make($orderItem->id.'.quantity_to_return')
                    ->label('Quantity to return/refund.')
                    ->numeric()
                    ->maxValue($orderItem->quantity)
                    ->suffix('/ ' . $orderItem->quantity)
                    ->live(),
                Placeholder::make($orderItem->id.'return_value')
                    ->label('Return value')
                    ->content(function() use ($get, $orderItem) {
                        return $get($orderItem->id.'.quantity_to_return');
                    }),
            ])
            ->columns(4);
        }
        
        return $fields;
    })
    ->action(function (array $data) {
        dd($data);
    }),

Actions\Action::make('process_return')
    ->form(function(Get $get, $record) {
        $fields = [];

        foreach ($record->items as $orderItem) {
            $fields[] = Group::make([
                Placeholder::make($orderItem->id.'product_title')
                    ->label('Product')
                    ->content(function() use ($orderItem) {
                        return $orderItem->product_title . ($orderItem->product_option_title ? ' - ' . $orderItem->product_option_title : '');
                    }),
                TextInput::make($orderItem->id.'.quantity_to_return')
                    ->label('Quantity to return/refund.')
                    ->numeric()
                    ->maxValue($orderItem->quantity)
                    ->suffix('/ ' . $orderItem->quantity)
                    ->live(),
                Placeholder::make($orderItem->id.'return_value')
                    ->label('Return value')
                    ->content(function() use ($get, $orderItem) {
                        return $get($orderItem->id.'.quantity_to_return');
                    }),
            ])
            ->columns(4);
        }
        
        return $fields;
    })
    ->action(function (array $data) {
        dd($data);
    }),

I am attempting to use Get $get($orderItem->id.'.quantity_to_return') to retrieve the quantity of items that are being returned so that I can show a preview of the $ amount that will be refunded. However, I am getting "$container must not be accessed before initialization" when attempting to call $get(). Is $get() not possible within a header Action? Any other way I can achieve this? Thanks

you can use $get in header actions. Does it work?

Actions\Action::make('customAction')
    ->form([
        TextInput::make('name')
            ->default(fake()->name)
            ->live(debounce: 800),
        Placeholder::make('output')
            ->content(fn(Get $get) => $get('name'))
    ]),

        TextInput::make('name')
            ->default(fake()->name)
            ->live(debounce: 800),
        Placeholder::make('output')
            ->content(fn(Get $get) => $get('name'))
    ]),
