GraphQL duplicate entries problem

Hi there, I believe that’s the default behavior for blocks that are server-side rendered and that contain inner blocks at the same time.

We’ve tested your use case in a different context, without Grids, and found out that what happens is the same: the renderedHtml field for such blocks already contains the whole rendered HTML, comprising inner blocks’ markup as well.

My advice is to handle the frontend rendering of grids/area blocks differently, only outputting the renderedHtml value, and not recursively parse their inner blocks.

Hope this helps!
