[tempo-distributed, grafana] How to enable traceQLStreaming getting error "rpc error: code = Unimplemented desc = unexpected HTTP status code received from server: 404 (Not Found); transport: received unexpected content-type "text/plain; charset=utf-8""

Hi, I am using grafana helm chart v7.3.11 and tempo-distributed helm chart v1.16.0.
I enabled traceQLStreaming through grafana.ini feature toggle options and after that when I query on Tempo data source, it does not give any result and throws the below error.
Do I need to do any configuration on Tempo as well to enable traceQLStreaming?

I am not sure what I am missing here to enable traceQLStreaming. Help would be much appreciated.
