I am creating a web application in .Net Core and for excel we are using Handsontable and it works fine.

Now when the user copy more than one row and only one place is there(last row remaining) then it shows us an error.

We have non-commercial-and-evaluation license key for educational purposes.

We also add this in our code for auto insert rows.

fillHandle: {
    autoInsertRow: true,
},

If anyone has answer then please let me know it help me a lot.
