Questions and Answers Strapi Backend

Hi! I have a “teaser” content type with a field “media” of type media. How can I filter teasers with the REST API that have an empty media field?

I tried /api/teasers?filters[media][0][$notNull]=true but it doesn’t work. There’s also no example in the docs: Filtering, Locale, and Publication State for REST API - Strapi Developer Docs

It is not possible to filter on dynamic zones or media fields
