Error: Introspection result missing directive locations

[noahemmet]

Hi! I'm upgrading to version 0.13.0 and I'm running into some issues with the build script. When I run it, I get the following error:

++ npx --no-install apollo codegen:generate Views/GraphQL/ViewQueries.generated.swift --target=swift '--includes=./**/*.graphql' --localSchemaFile=Views/GraphQL/Schema.json --passthroughCustomScalars

Loading Apollo Project [started]

CLIError: Error in "Loading schema for Unnamed Project": Error: Introspection result missing directive locations: { onField: true, onOperation: false, args: [[Object]], name: "include", description: "Directs the executor to include this field or fragment only when the `if` argument is true.", onFragment: true }

Loading Apollo Project [failed]

My build script is set up like so:

cd "${SRCROOT}"
$APOLLO_FRAMEWORK_PATH/scripts/check-and-run-apollo-cli.sh codegen:generate "Views/GraphQL/ViewQueries.generated.swift" --target=swift --includes=./**/*.graphql --localSchemaFile="Views/GraphQL/Schema.json" --passthroughCustomScalars

A few notes:

• I'm using Xcode 13 and Swift Package Manager, which was working with version 0.12.0.
• I'm not using any @directives in my .graphql files.
• The backend is running SwiftGraphQL, so it's possible it's generating a Schema.json file that's incompatible with the latest Apollo code gen?
• I've tried various combinations of quotes/no-quotes, removing --passthroughCustomScalars, and some --includes path globs.

Any ideas? Thanks!

Looks like the error message was added in graphql/graphql-js#1429, in response to dotansimha/graphql-code-generator#556 (comment).

So yeah, I think it's a backend issue. It's a bit late over here and I'm a bit blurry, so I'll tackle this in the morning, but any thoughts on how much backend work this might be? I can't tell how much the introspection schema's changed since last year, heh…

Definitely seems like the error is in parsing the schema - if you try to parse it locally using the apollo CLI, is it parsing?

I honestly haven't the faintest idea how much work that is on the BE, I'm pretty purely a mobile dev. I know the team has tried to keep the changes as minimal as possible but I'd look at the migration guides from 1.x to 2.x for the CLI, that might have some suggestions

@noahemmet Since it seems like this is an issue with some combo of backend and tooling rather than with iOS specifically, do you mind if we close this out?

[noahemmet]

do you mind if we close this out?

Go for it!

Figured it out! The Vapor extension I was using wasn't including the directives field in the introspection query: StevenLambion/GraphQLRouteCollection#3

Ooh! Neat project 🤓
