Importrange internal error in Google Spreadsheet

I am trying to import data from one Google Sheet to another sheet using import range function, my data is not that large to break it only has four column and rows is 2000 than also when am importing that amount of data then also that function is showing import range internal error.
I even try the given method in below link but that also not working using iferror function than also it is showing import range internal error.
Is there any solutions for this or any other way to import the data from one sheet to another?
I have also used coupler.io extension that also didn't do well on my sheet.

Using Iferror
