In Ignition 8.0.9, when I restart the server I see this error in logs.:
Cannot coerce value '{“columns”:[{“name”:“Fecha_Hora_Ejecucion_Ciclo”,“type”:“java.util.Date”}, {“name”:“Segundos_Duracion_Ciclo”,“type”:“java.lang.Float”}],“rows”:[[“Wed Mar 04 18:03:52 GMT 2020”,0.0]]}’ into type: interface com.inductiveautomation.ignition.common.Dataset
I have verified it in two Gateways: Windows 10 and Windows Server 2016. It is important to know that I am in Spain and that the operating systems are configured in language and format Spanish. Maybe that is the origin of the incident.
I believe this is related to a known bug that’s slated to be fixed pretty soon, but I can’t guarantee that. I would recommend getting in contact with support - they can either confirm it’s the same known issue, or file a new bug ticket for you.
You should be aware that bug fixes don’t happen in hours or even days. They take weeks or sometimes months. If this is code that worked on previous version of Ignition, revert to that version. If this is code that has never worked, you might want to use a work-around (like a string column type) until a bug fix is available. IA doesn’t have a stock of magic wands. (It’d sure be nice, though.)
