Why Google sheets missing the last email when sending emails? - google-apps-script

Question

my google sheet will email a PDF copy of the sheet to a list of 4 emails ( in cells L5:L8 )
but it seems that the email in cell L8 never picked , logger shows it in the array ! .
see my code and help figuring the problem !? I'm suspecting something wrong in my FOREACH loop .
function onEdit2(e) {
var sheet = SpreadsheetApp.getActiveSheet();
var r = sheet.getRange('L11').getValue();
if (r == "Send") {
var ss = SpreadsheetApp.getActiveSpreadsheet()
var ssID = ss.getId();
var sheet = ss.getActiveSheet();
var sheetName = ss.getName();
var key = SpreadsheetApp.getActiveSpreadsheet().getActiveSheet().getName();
var token = ScriptApp.getOAuthToken();
var setcolor= SpreadsheetApp.getActiveSheet().setTabColor("#0000A0");
var emails= sheet.getRange("L5:L8").getValues();
var subject = "Daily report ";
var body = "Please find the attached" +" "+ key ;
var url = "https://docs.google.com/spreadsheets/d/"+ssID+"/export?"
+ "format=xlsx" + "&gid="+sheetgId+ "&portrait=true" +
"&exportFormat=pdf";
var tempSheet = ss.insertSheet("tempSheet"); // Added
sheet.getRange("A1:J27").copyTo(tempSheet.getRange(1, 1)); // Added
SpreadsheetApp.flush(); // Added
var sheetgId = tempSheet.getSheetId(); // Added
var url = "https://docs.google.com/spreadsheets/d/"+ssID+"/export?" + "format=xlsx" + "&gid="+sheetgId+ "&portrait=true" + "&exportFormat=pdf";
var result = UrlFetchApp.fetch(url, {headers: {'Authorization': 'Bearer ' + token}});
var contents = result.getContent();
emails.forEach(function(email){
MailApp.sendEmail(email.toString(),sheetName ,body, {attachments: [{fileName: sheetName + ".pdf", content: contents, mimeType: "application//pdf"}]});
ss.deleteSheet(tempSheet); // Added
})
}
var sheets = SpreadsheetApp.getActiveSpreadsheet().getSheets();
for ( var i = 0 ; i<sheets.length ; i++) {
var sheet1 = sheets[i];
sheet1.getRangeList(['L3','L11']).clearContent();
}
}
