Description (last modified by SergeyBiryukov)

In wp-includes/script-loader.php near line 2406 within function wp_global_styles_render_svg_filters() the function get_current_screen() can be null causing a null pointer.

Proposal is to add a null check before use:

if (
        is_admin() &&
        get_current_screen() != null &&
        ! get_current_screen()->is_block_editor()

PHP does not have the concept of a null point error.

I presume you mean you are seeing a "passing null to non-nullable" deprecation notice on PHP 8.1 ?

  • Resolution set to wontfix
  • Status changed from new to closed

The wp_global_styles_render_svg_filters() function where this error occurred is deprecated in WP 6.3 via [56101] / #58555.

The issue within the function is not fixed. However, Core no longer calls this function. Since it's deprecated, it should no longer be used.

I'll close this ticket as wontfix. I'm using that resolution type because the function itself will not be changed now that it's deprecated.

Thank you everyone for your contributions!
