I get this error when trying to set window.location to result.href() but only in IE. Everything works fine in Chrome or Firefox. ``` javascript var data_arr = factory.prepareData(data, coldefs); var sheet = { creator: userCredentials.Name, lastModifiedBy: userCredentials.Name, worksheets: [ { data: data_arr, table: true, name: name } ] }; window.location = xlsx(sheet).href(); ``` is how i'm creating the sheet.
