Expected behavior

Compilation successful or raises an error

Actual behavior

Compilation stuck with Compiling lib/app_web/api/schema.ex (it's taking more than 10s) until consumes all available memory and gets killed by OOM

Relevant Schema/Middleware Code

I would like to share the details if you can point to what can I share. I have a huge and private gql project where this is happening, and I just don't know what should I share. The diff which breaks the code has introduced a few unions, objects, enums and one import_types and relay connection without anything special

[hissssst]

Oh, I've found the root cause. It happens when you add import_types into the module where you import types from, and not in the schema, where it is supposed to be used in

@benwilson512 why did you close it as completed? Reopen please

[hissssst]

@benwilson512 ping

[benwilson512]

Hi @hissssst sorry when you indicated that you found the root cause I took that to mean that you had solved the issue. Are you asking Absinthe to detect such cases proactively and raise an error?

[hissssst]

Yes, exactly. This is even in the issue

Expected behavior
Compilation successful or raises an error
