I am using the "Data grid2" widget with the "JS: Export_To_Excel"  from "DataWidgets".   Where Mendix Studio Pro did not throw an error , but at runtime, when I press the "call Nanoflow Button" that calls "Export_To_Excel",   I get the following error: An error occurred while executing an action of Main.CQPDatabase_Overview.actionButton1: Cannot read properties of undefined (reading 'toNumber')   Nanoflow stack:  "Call JavaScript Action: DataWidgets.Export_To_Excel" in nanoflow "Main.ACT_CQPDatabase_toExcel"   at http://localhost:8080/mxclientsystem/mxui/mxui.js?638567435886998972:61:176091   at ye (http://localhost:8080/mxclientsystem/mxui/mxui.js?638567435886998972:19:6830)   at i (http://localhost:8080/mxclientsystem/mxui/mxui.js?638567435886998972:19:6731)  at O (http://localhost:8080/mxclientsystem/mxui/mxui.js?638567435886998972:59:5099)   I am not using any Custom content Columns in the data grid2. How do I fix it?

We ran into this issue on the latest version of Data Widgets.  We originally did not pass a ChunkSize to Export_To_Excel and left it empty.  This seems to throw this error now and it requires an integer.  This is the number of rows it processes at a time, you will sometimes notice a progress bar when exporting a large amount of rows.  I seem to get the fastest exports using 500 for this number in my testing.

 

You can also downgrade to Data Widgets v2.20.1, which still allows the empty value on ChunkSize.
