The format of the logs suggest that it's coming from a package dependency and not from within Lily's runtime (which defines the log format for all components within).

If I had to guess: Lotus uses OpenCensus for exporting traces, whereas Lily uses OpenTelemetry and it may be the case the tracing provider expected by Lotus is incompatible with the one used by Lily.
