Error when creating pivot table - google-apps-script

Question

I am trying to create a pivot table using Google Apps Script. Once the script below runs, there is no output and an error is shown:
ReferenceError: "Sheets" is not defined. (line 50, file "Code")
function createPivotTable() {
var ss = SpreadsheetApp.getActiveSpreadsheet();
// The name of the sheet containing the data you want to put in a table.
var sheetName = "Data";
var pivotTableParams = {};
// The source indicates the range of data you want to put in the table.
// optional arguments: startRowIndex, startColumnIndex, endRowIndex, endColumnIndex
pivotTableParams.source = {
sheetId: ss.getSheetByName(sheetName).getSheetId()
};
// Group rows, the 'sourceColumnOffset' corresponds to the column number in the source range
// eg: 0 to group by the first column
pivotTableParams.rows = [{
sourceColumnOffset: 2,
sortOrder: "ASCENDING"
}];
// Defines how a value in a pivot table should be calculated.
pivotTableParams.values = [{
summarizeFunction: "COUNTA",
sourceColumnOffset: 2
}];
// Create a new sheet which will contain our Pivot Table
var pivotTableSheet = ss.insertSheet();
var pivotTableSheetId = pivotTableSheet.getSheetId();
// Add Pivot Table to new sheet
// Meaning we send an 'updateCells' request to the Sheets API
// Specifying via 'start' the sheet where we want to place our Pivot Table
// And in 'rows' the parameters of our Pivot Table
var request = {
"updateCells": {
"rows": {
"values": [{
"pivotTable": pivotTableParams
}]
},
"start": {
"sheetId": pivotTableSheetId
},
"fields": "pivotTable"
}
};
Sheets.Spreadsheets.batchUpdate({'requests': [request]}, ss.getId());
}

I just had the same issue. I was missing Google Sheets API
https://developers.google.com/sheets/api/quickstart/apps-script
After enabling, script finally worked.
