📌 Support views default display Active had a MR which enables search api to use the default display too.

So did some initial testing and ran into a bef fatal error that will address here 🐛 BEF php 8.1.2 / TypeError: count(): Argument #1 ($value) must be of type Countable|array, null given Needs work

So added a facet for content types. The facet appears fine and settings appear to work. But the actual filter doesn't appear to work

"The submitted value article in the type element is not allowed."

Scratch that I needed to apply fix for 🐛 Argument #1 ($value) must be of type Countable|array, null given in count() (line 57 of core/lib/Drupal/Core/Render/Element/Radios.php). Needs work

I think the error there happens when there are no facets, and it's still converted into a checkboxes or similar element without any options.

Yea I have a fix for bef I can push that helps until it’s fixed in core.

So this feature is working as expected. Like the simplicity of integrating with views and rendering control by bef
