Hello, I'm seeing an error related to GraphQL when running 
./pants test ::
. It seems to come from the ariadne package, and looks as follows.
Copy code
E   graphql.error.syntax_error.GraphQLSyntaxError: Syntax Error: Unexpected <EOF>
E
E   GraphQL request:238:1

I've pasted the stack trace in the thread to avoid myself from adding a super long message into the channel. I initially suspected this may be some issue related to ariadne not specifying their dependencies correctly. Previously, I've added to the 
overrides
field of the 
pipenv_requirements
target in the root 
BUILD
file in order to resolve those types of issues, e.g.
Copy code
pipenv_requirements(
    ...
    overrides = {
        "google-cloud-pubsub": { "dependencies": [":requirements#setuptools"] },
    }
)
However, the error message is not easy for me to understand in this case, and I can't quite tell what kind of error this is, and whether it is due to the same root cause. I'm wondering if the Pants engineering team has any tips on how I can diagnose what is going wrong here and how I could go about trying to resolve this. I've already run the following, and see that ariadne is at the very least correctly listed as a dependency of my target.

It looks like an issue with the contents of a gql string in 
tests/functional/interaction_history/test_interaction_history_utils.py
?
The traceback is in a GraphQL parser, trying to parse a GraphQL document… so most likely a typo in that area, I’d guess.

When I run the test via 
pytest
, it works fine. But running via 
./pants test ::
causes this exception to be raised...
😲 1
Okay, I think I figured it out. This is because I was using 
ariadne.load_schema_from_path
, which reads 
*.graphql
files from directories, which would fail if they aren't added as explicit dependences 😞

Makes sense, yes.
