Estoy usando LockService cuando envío correos electrónicos, pero cuando varios usuarios lo ejecutan al mismo tiempo, arroja el error: Service invoked too many times...

Aquí hay un registro que muestra las fallas:

 function sendEmail() { const ss = SpreadsheetApp.getActiveSpreadsheet(); var lock = LockService.getScriptLock(); try { lock.waitLock(3000); // wait 03 seconds for others' use of the code section and lock to stop and then proceed } catch (e) { Logger.log('Someone has just sent an Email. Try it again 3 seconds later.'); return HtmlService.createHtmlOutput("<b> Server Busy please try after some time <p>") // In case this a server side code called asynchronously you return a error code and display the appropriate message on the client side //return "Error: Server busy try again later... Sorry :(" } /* Gets certain data from current row. These are used as criteria */ GmailApp.sendEmail(email, "Text", name + " BODY.", { name: 'Diplay Custom Name as Sender' }); //Looks for a matching record in another sheet to mark its adjacent column as sent ("Yes") for (var n = 0; n < formRespValues.length; n++) { if (formRespValues[n][1] == testNo) { formRespSheet.getRange('M' + (2 + n)).setValue('Yes'); } } } SpreadsheetApp.flush(); // applies all pending spreadsheet changes lock.releaseLock(); }
