Filtering records with images gives false positives

How can we help you?

My parts resource has a FileUpload field for images:

FileUpload::make('images')
    ->image()
    ->multiple()
    ->maxFiles(12)
    ->reorderable()
    ->appendFiles()
    ->openable(),                        

This corresponds to a json column in my parts table.

I have a separate public-facing Filament table with a ternary filter on images:

TernaryFilter::make('images')
    ->label('Has images')
->nullable(),

The problem is that, in some cases, the column contains an empty array, denoted by square brackets "[]", which is interpreted as not empty by the filter.

This results in records without images being included when they shouldn't be.

I've tried this:

TernaryFilter::make('images')
    ->label('Has images')
    ->query(function (Builder $query, array $data): Builder {
        $selected = $data['value'] ?? null;
        if ($selected === false) {
            $query->whereNull('images');
        } elseif ($selected === true) {
            $query->whereNotNull('images');
        }
        return $query;
    })
->nullable(),

But get the same result.

Same for this:

TernaryFilter::make('images')
    ->label('Has images')
    ->query(function (Builder $query, array $data): Builder {
        $selected = $data['value'] ?? null;
        if ($selected === false) {
            $query->whereNull('images')
                ->orWhere('images', '=', '[]')
                ->orWhere('images', '=', '');
        } elseif ($selected === true) {
            $query->whereNotNull('images')
                ->where('images', '!=', '[]')
                ->where('images', '!=', '');
        }
        return $query;
    })
->nullable(),

My Part model casts images to an array:

protected $casts = [
    'custom_fields' => 'array',
    'images' => 'array',
    'documents' => 'array',
    'videos' => 'array',
];

Any ideas on how to fix this?
