…2195) ### 📝 Description If an introspection query runs against a schema where all fields on an object are deprecated then an empty object is returned which will fail to print via graphql-java when doing `SchemaPrinter(options).print(graphQLDocument)` which is done in the graphql-kotlin client. By including those deprecated fields, we avoid the invalid object. Stack trace example: ``` Caused by: graphql.schema.validation.InvalidSchemaException: invalid schema: "InputTypeWithAllDeprecatedFields" must define one or more fields. at graphql.schema.GraphQLSchema$Builder.validateSchema(GraphQLSchema.java:886) at graphql.schema.GraphQLSchema$Builder.buildImpl(GraphQLSchema.java:874) at graphql.schema.GraphQLSchema$Builder.build(GraphQLSchema.java:841) at graphql.schema.idl.SchemaGenerator.makeExecutableSchemaImpl(SchemaGenerator.java:143) at graphql.schema.idl.SchemaGenerator.makeExecutableSchema(SchemaGenerator.java:113) at graphql.schema.idl.SchemaGenerator.makeExecutableSchema(SchemaGenerator.java:84) at graphql.schema.idl.UnExecutableSchemaGenerator.makeUnExecutableSchema(UnExecutableSchemaGenerator.java:28) at graphql.schema.idl.SchemaPrinter.print(SchemaPrinter.java:496) at com.expediagroup.graphql.plugin.client.IntrospectSchemaKt$introspectSchema$2$1.invokeSuspend(introspectSchema.kt:182) at kotlin.coroutines.jvm.internal.BaseContinuationImpl.resumeWith(ContinuationImpl.kt:33) at kotlinx.coroutines.DispatchedTask.run(DispatchedTask.kt:104) at kotlinx.coroutines.EventLoopImplBase.processNextEvent(EventLoop.common.kt:277) at kotlinx.coroutines.BlockingCoroutine.joinBlocking(Builders.kt:95) at kotlinx.coroutines.BuildersKt__BuildersKt.runBlocking(Builders.kt:69) at kotlinx.coroutines.BuildersKt.runBlocking(Unknown Source) at kotlinx.coroutines.BuildersKt__BuildersKt.runBlocking$default(Builders.kt:48) at kotlinx.coroutines.BuildersKt.runBlocking$default(Unknown Source) at com.expediagroup.graphql.plugin.client.IntrospectSchemaKt.introspectSchema(introspectSchema.kt:150) at com.expediagroup.graphql.plugin.gradle.actions.IntrospectSchemaAction.execute(IntrospectSchemaAction.kt:37) ``` And an example schema that causes the problem: ```sdl schema { query: Query } type Query { hello(input: HelloInput): String! } input HelloInput { legacyField: String @deprecated(reason: "Use `newField` instead.") } ``` ### 🔗 Related Issues
