Review Comment:
   I see, this is an edge where we don't even reach real dag monitoring then
   not sure where the diagnostics object is used, but does it make sense to use 
the full trace, like:
   ```
   String reportedException = "Execution has failed, stack trace: " + 
ExceptionUtils.getStackTrace(e);
   console.printError(reportedException);
   diagnostics.append(reportedException);
   ```
