Require argument for custom filter

[alifs-dev]

Hello,
I've a custom filter with a topic parameter.
When i call the endpoint /articles/latest, when topics parameter is not required, the default api platform controller is executed.
But when i fill the topics parameter, the filter class is executed.
Is it normal ?

Thanks

 *         "filters"={ArticlesFilter::class},

 *             "path"="/articles/latest",

"filters"={ArticlesFilter::class},

I've never seen this, do you want to use the @ApiFilter annotation instead?

it come from the documentation: https://api-platform.com/docs/core/filters/
I'll try with annotation
thanks

Closing, as there were no recent activity.

The "old" syntax is documented (here)[https://github.com/api-platform/docs/blob/f098c3a269b8466709c374262534f472c32f0130/core/filters.md#search-filter] and you can also find a bunch of example in the core test suite.
