Actually this error code is more a warning for the developers. It is not an indicator of good or bad processing.
It is something that should be hidden or more like a warning (in orange instead or red). At the moment it is kind of misleading for the users. This error message should be investigated only if the user experiences a crash or bug.
Is it your case? Are you able to load all the results properly in the different view (rayCloud, Mosaic Editor…)?
Do you notice anything wrong when the processing of all steps is 100% completed?
If so, please send us a request with details about your project, together with the log file that you can find here:
