  a!forEach(
    items: index(local!excel,"result","values",{}),
    expression: {
      ProductID: index(fv!item,1,""),
      VendorID: index(fv!item,2,""),
      ProductCategory: index(fv!item,3,""),
      ProductName: index(fv!item,4,""),
      CurrentPrice: index(fv!item,5,""),
      NewPrice:index(fv!item,6,""),

We have to upload the excel and then only it should display, while using this rule in interface, it is showing same error in interface, so then we couldn't add the file 

It is giving the error because readExcelSheet is looking for the file and it is not there. Try to do null check for the file.
