Laravel – Attempt to read property "slug" on null

I’m encountering an issue in my Laravel application when I try to access the URL https://example.com/sitemaps.xml. The error message I receive is ‘Attempt to read property "slug" on null’.

The error seems to be originating from the following line in my resources/views/default/sitemaps.blade.php file:

{{ url('category', [$subcategory->category->slug, $subcategory->slug]) }}

Can anyone help me understand why this error is occurring and how I can resolve it?

    try this

    @if ($subcategory->category)
{{ url('category', [$subcategory->category->slug, $subcategory->slug]) }}
@endif

    and make sure that $subcategory->category is not NULL

    The above error occurs when accessing the slug property from a null category object. Here are two possible solutions:

    For PHP v8 or above

    {{ url('category', [$subcategory->category?->slug, $subcategory->slug]) }}

    For PHP v7 or above

    @if ($subcategory->category)
    {{ url('category', [$subcategory->category->slug, $subcategory->slug]) }}
@endif
