Column/Filter datatype is empty in external data report implemented by Add-In

$

Topic by Sophia Cai

I am following the Analytics for External Data section in documentationto create an add-in to get external data in report. I can run the report and get the external data.

However, when I run the report in dashboard, it pops up error "mode=INT_BUF, pair 'data_type' is required".

I checked the report definition and realized that the data type of columns and filters are empty. And in report definition xml, it shows <data_type>0</data_type>.

I have defined the column type in Add-In code following the documentation:

                    this.Columns.Add(new ReportColumn()
                    {
                        DataType = ReportColumnType.String,
                        Label = "Agent Name",
                        Name = "AgentName",
                        CanDisplay = true
                    });
 
Should I define anything else to set the data type in report? How can I solve the problem?  
 
Thanks,
Sophia
