Loki Trace to Logs Multiline Not shown in Grafana

Hi All,

I have configured multi-line regex in my promtail and I can see that the stack traces from my application are in a single line in Grafana. However, when I filter on say a trace_id in Grafana (Trace to Logs), the multi-line lines are no longer shown.

I know the multi-line logs are present in Loki because I can see them when filtering on the job in the log browser. Only when I go from Trace to Logs does this issue occur.

Any thoughts?

Thanks
