Empty Report (Data item not defined for this template)

[peerendig]

Hello,

i try to implement a sql query to my report.

the script that i use is from here:
https://jsreport.net/blog/pdf-reports-in-sql-server#prepare-input-data-source

but i get a empty report.

Please try to isolate the problem. For example, try to explicitly set the data inside the script. Add some console.logs...
Or provide playground demo I can check.
