Client can't deserialize GraphQL response

See original GitHub issue

Hi, I’m having some trouble with the GraphQL client (version 3.6.1). I’m getting an exception when GraphQLClient is trying to deserialize the response data to GraphQLResponse<HubCheckOut.Result>. The model itself looks fine and matches the JSON, but for some reason Jackson is not able to map it.

If I use a debugger to manually serialize to Map<String, Any> with the mapper it works, so the JSON is fine. Any ideas?

This is the generated model class:

const val HUB_CHECK_OUT: String =
    "mutation HubCheckOut(${'$'}hubID: ID!, ${'$'}employeeID: ID!) {\n    insertHubCheckedOutLogRecord(input: {hubId: ${'$'}hubID, employeeId: ${'$'}employeeID}) {\n        record {\n            shiftId\n        }\n    }\n}"

class HubCheckOut(
  private val graphQLClient: GraphQLClient<*>
) {
  suspend fun execute(variables: HubCheckOut.Variables, requestBuilder: HttpRequestBuilder.() ->
      Unit = {}): GraphQLResponse<HubCheckOut.Result> = graphQLClient.execute(HUB_CHECK_OUT,
      "HubCheckOut", variables, requestBuilder)

  data class Variables(
    val hubID: ID,
    val employeeID: ID
  )

  data class ShiftStateHubLogRecord(
    val shiftId: ID?
  )

  data class InsertHubLogCheckedOutRecordResponse(
    val record: HubCheckOut.ShiftStateHubLogRecord
  )

  data class Result(
    val insertHubCheckedOutLogRecord: HubCheckOut.InsertHubLogCheckedOutRecordResponse?
  )
}

And the exception:

Strange Map type java.util.Map: cannot determine type parameters
 at [Source: (String)"{"data":{"insertHubCheckedOutLogRecord":{"record":{"shiftId":"6387e498-2ac2-3c76-9b9e-f5248a348f8b"}}}}"; line: 1, column: 1]

How did you do the force-downgrading?

I added this explicit import in my build.gradle:

implementation('com.fasterxml.jackson.core:jackson-databind:2.11.1') {
    version {
        strictly "2.11.1"
    }
}
