Hello i’m encountering an error when running

graphqlIntrospectSchema

in the 6.0.0-alpha.0 version. I’ve started my gql server and then i’m running

./gradlew graphqlIntrospectSchema --endpoint="<http://localhost:12017/api/public/graphql>"<http://localhost:12017/api/public/graphql>

but this is failing with the following exception:

Execution failed for task ':graphqlIntrospectSchema'.
> There was a failure while executing work items
   > A failure occurred while executing com.expediagroup.graphql.plugin.gradle.actions.IntrospectSchemaAction
      > Unable to run introspection query against the specified endpoint=<http://localhost:12017/api/public/graphql>

No transformation found: class io.ktor.utils.io.ByteBufferChannel -> class kotlin.collections.Map
with response from <http://localhost:12017/api/public/graphql>:
status: 200 OK
response headers: 
Vary: Origin

Any suggestions on what I’m doing wrong?

hello 👋 this sounds like a potential classpath issue. If you could open an issue and provide a repo that reproduces that issue it would be great. side note: I got an open PR that bumps up ktor dependency to 2.0 (another alpha will be cut once the batching and dep update PRs are merged) which may fix the issue

signing off for fit the night, but will create a repo tomorrow

Hi 👋 sorry I'm coming back to this a bit later. I've created a repo that reproduces this error, using version

6.0.0-alpha.1

, and added the full logs in an issue: here

👋 Thanks for the code example but I don't think it reproduces your issue -> in your example project you have misconfigured

graphql-kotlin

plugin Since you are configuring

graphql { client { .... }}

it will attempt to add corresponding tasks as a compile dependency. When you attempt to build/run your app it attempts to run introspection against

localhost:8080/graphql

which at that point in time does not exist yet - hence the

Unable to run introspection query against the specified endpoint=<http://localhost:8080/graphql>

Sorry about mixing those things up. Thanks for your explanation, makes sense and it clarified things for me. Setting up

content type

on the response fixed the introspection issue:

call.respondText(jsonString, ContentType.Application.Json)

and after I had the schema and added the graphql queries to

resources

, I managed to get the graphql plugin to generate the files. I've pushed the fix to that repo as well. Thank you very much 🙏

awesome 👍
