I had a test case working fine, but after adding an extra parameter tiger to my method swiming, it's breaking.
I even passed the new parameter tiger to my test case but still it's breaking.
update I am getting grid undefined at this line...any idea now how to proceed let grid = $('#henTigerGrid').data('kendoGrid');
let tiger = { "nail": "hens/v1/sky/88888888888888", "columns": [], "title": "DOCUMENTS", "excelFileName": "ViewAiringsExport", "mainId": 88888888888888 }; Code is below:

In your function you use a jQuery lookup $('#henTigerGrid').data('kendoGrid'); for an element with the id #henTigerGrid which is not defined in the provided unit test. A few lines below you try to access a property _data of the lookup which then fails.
This is an typical example for wrong use of a service locator pattern (which jQuery lookups essentially are). They introduce hidden, untyped dependencies which bite you later (see your current problem). If you would use a more dependency injection style, the attributes value (or the Dom element itself) would be passed as a dependency (here a declared parameter) to the function. Like that the error could even occur in the first place since you would not miss a missing parameter.

hey I found it if I remove this line error is getting fixed
"skyId": this._dataSource._data.length + 1, Answers 3
I believe_dataSource is not set correctly, therefore, you can't access it's array _data
