Hi @soyuka I'm getting multiple issues with the auto generated documentation for Filters.
One of them is the fact we cannot override the description manually with the following syntax

'brandWithDescription' => new QueryParameter(
      filter: new ExactFilter(),
      description: 'Extra description about the filter',
),

Without this fix you're getting '' as description...

#7634 helped to find the fix and the test to write.

Thanks @VincentLanglet I took the liberty of changing the approach by modifying the OpenApiFactory instead of the filters! Waiting for CI before merging.

Thanks.

Seems like the failure is failing now then. I let you choose if it's an expected (new) behavior then :)

thanks!
