After updating to hotfix 14.0.6 HF-023 you might see the following error when using the R service:
Error from Remote Service: Internal Server Error (500) - JSON parse error: Unrecognized field "settings" (class com.tibco.spotfire.topology.domain.EnginePayloadAnalyticSpecification), not marked as ignorable
at Spotfire.Dxp.Data.DataFunctions.Executors.RemoteServiceClient.RunFunction(DataFunctionInvocation invocation)
at Spotfire.Dxp.Data.DataFunctions.Executors.SPlusFunctionExecutor.<ExecuteFunction>d__9.MoveNext()
at Spotfire.Dxp.Data.DataFunctions.DataFunctionExecutorService.<ExecuteFunction>d__8.MoveNext()
This issue is fixed by applying version 1.17.7 or higher of the R-service.
