Hi, I'm following: https://help.liferay.com/hc/en-us/articles/360039026252-Filter-Sort-and-Search, but I'm able to filter only first level fields.

I'm trying to query blogPostings adding a filter on taxonomyCategoryBriefs with taxonomyCategoryId = X, but I get "HTTP 400 Bad Request"

This is my data without filter:

{
  "data": {
    "blogPostings": {
      "items": [
        {
          "id": 38326,
          "headline": "Liferay Post",
          "articleBody": "<p>Lorem ipsum dolor sit amet, consectetur adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. Ut enim ad minim veniam, quis nostrud exercitation ullamco laboris nisi ut aliquip ex ea commodo consequat. Duis aute irure dolor in reprehenderit in voluptate velit esse cillum dolore eu fugiat nulla pariatur. Excepteur sint occaecat cupidatat non proident, sunt in culpa qui officia deserunt mollit anim id est laborum.</p>",
          "taxonomyCategoryBriefs": [
            {
              "taxonomyCategoryId": 38437,
              "taxonomyCategoryName": "Liferay"
            }
          ],
          "image": {
            "contentUrl": "/documents/38334/38340/liferay.png/ae6992f2-c36a-03ff-89af-d6fc09112041?t=1616148845617"
          }
        }
      ]
    }
  }
}

This is the query with the filter:

query Category {
    blogPostings(siteKey: "20121", filter: "taxonomyCategoryBriefs/any(c: c/taxonomyCategoryName eq 38437)"
    ) {...}

Any idea? Or is there another method to get all posts of a category?

Thanks
