Federation: query for external entity not working

pkeeley opened this issue 2 years ago · comments

I have attached a small project with two files, apollo.js and mercurius.js. Both set up a small federation. Running this query against Apollo returns the expected results, mercurius does not. Mercurius also makes extra calls (which is why it is not returning the correct results).

Mercurius makes the following calls:

Query.userByPost
User.posts
Posts already there
User.posts
Posts already there
2 x User.__resolveReference
2 x User.posts

Apollo makes these:

Query.userByPost
User.posts
Posts already there
User.posts
Posts already there

Apollo doesn't resolve the reference or call User.posts the third and forth time.

query { userByPost(ids: ["u1","u2"]) { id posts { pid title content } } }
