GraphQL or API are not returning every entry in a collection type

System Information
  • Strapi Version: v5.0.3
  • Operating System: Mac
  • Database: GraphQL
  • Node Version: v18.17.0

I recently migrated a blog over to a new Strapi Cloud backend and noticed right before my planned launch that of the 330 imported entries in my “Blog Post” collection type, only 141 were being brought in by my GraphQL queries (I’m building my blog with Gatsby and the gatsby-source-strapi plugin). From what I can tell, it seems random what is appearing the query and what isn’t. Newly created posts are ignored, clones of working posts are also ignored and when I unpublished a post that did work and then republished it, it no longer appeared.

Any sort of help or advice would be really appreciated. I’m new to Strapi and truly baffled.
