I found an issue on latest Mango version 1.13.0.
When you export and then import data points from a Modbus datasource, import task return an error about ChartRenderer property:
Data point 'DP_347885': 'JsonException reading property 'chartRenderer' of type null', caused by: 'null'
It seams it couldn't parse 'null' value of chartRenderer property. What I have to do is set this property to a different value, for example
The workaround works and using Search-and-Replace feature of every text editor I managed to import saved configurations.
Anyway it is quite annoying to set this property, because I don't use it at all..
When will be release next Mango version?
Best regards and thank you
