Intended outcome:

I am intending to export my graphql types to typescript types using apollo client:codegen --target typescript I expect to generate types in the generated folder My Apollo client is running on @apollo/client v3.0.beta

Actual outcome: I get the following error

    at getValidationErrors (node_modules/apollo-language-server/lib/errors/validation.js:25:20)
    at Object.validateQueryDocument node_modules/apollo-language-server/lib/errors/validation.js:30:34)
    at Object.generate [as default] (node_modules/apollo/lib/generate.js:23:18)
    at write node_modules/apollo/lib/commands/client/codegen.js:78:54)
    at Task.task (node_modules/apollo/lib/commands/client/codegen.js:98:46)

@anark I faced this issue when using graphl@15 dependency. I believe if you downgrade to version graphql@14, will sove the issue.

That did the trick in my case.

Downgrading to graphql@14 solved this. Is there anyway to fix this to make it compatible with graphql@15?

[juliovedovatto]

@abernix I noticed your made a new release of apollo-language-server, but I'm still getting error when using codegen with typescript support, using graphql@15.0.0

This line: https://github.com/apollographql/apollo-tooling/blob/master/packages/apollo-language-server/src/errors/validation.ts#L63

TypeError: context.getErrors is not a function

Could you take a look, please?

PS: graphql@14.6.0 works fine

Just an update: I was following #1908 and now I'm using apollo@next package.

It is working with GraphQL 15 as expected for the project I'm working on.

[trevor-scheer]

Thanks for the update @juliovedovatto! I'm preparing the release to latest as we speak, so expect to see apollo@2.29.0 in the next 10 minutes or so.
