Example w-graphql-subscription is broken
aantron opened this issue · comments
Repro:
- On
master,cd example/w-graphql-subscription. dune exec ./graphql_subscription.exe- Visit
http://localhost:8080/in a browser. - Click "play" in the GraphiQL IDE that appears.
Result in GraphiQL:
{
"errors": [
{
"message": "Field 'users' is not defined on type 'query'"
}
]
}
By contrast, the query works in the playground, which is using an older version of Dream (and dependencies).
It seems I cannot reproduce the problem:
Browser: Firefox, Brave
OS: Ubuntu 22.04.2 LTS
Commit: Master HEAD / dbf01b8
Very interesting, thanks! I am still getting this:
Also Ubuntu 22.04.2 LTS, browser Brave.
Could you show what OCaml packages you have installed? I suspect this might be an issue with GQL upstream.

Also, I did try this specifically on dbf01b8 for good measure, but it's broken on all recent commits in master for me.
I had a switch with 4.14 compiler and I saw you're using OCaml 5 so I created a clean switch with OCaml 5.
My list looks a bit different. I installed the deps as documented:
opam install --deps-only ./dream.opam --with-test

Additionally, I made sure not to run any esy commands in w-graphql-subscription. Right after deps installation,
I navigated into the dir and ran dune exec ./graphql_subscription.exe. Still works as expected.
Thanks @laaksonel! My query was different. I assumed that this example was self-contained, but it looks like the query was being taken from local storage from example i-graphql. Ideally, the GraphiQL served by Dream's examples wouldn't cache the query. However, that's also the same GraphiQL that is built into Dream for users' development needs.
