Suggestion: On the backend side, migrate @ Log lombok annotations (which uses java util logging) to @ Slf4j (or @ logback) instead.
This will help us in better logging our excpetion, by logging full stack traces for instance (by adding the source exception as last parameter).
However, it may not be fully transparent: first, the severe loggers will probably have to be replaced by error, and second, it may impact the way we push logs to grafana. To check and analyse.
