I have 9 separate scripts setup to import CSV attachments from GMAIL to Google Sheets every 5 minutes. I prefer to do this more often, but received a temp ban when trying to execute these every minute. I would also like to eliminate this error if possible: TypeError: Cannot call method "getMessages" of undefined. which is returned when there is no email present to process.
Is there a way to execute each script together with one GMAIL API call as opposed to 9 separate? Same email address, different labels per script. Here's 2 of the 9 scripts executed every 5 minutes:
function STSalesImportFromGmail() {
//gets first(latest) message with set label
var threads = GmailApp.getUserLabelByName('Streeterville Sales').getThreads(0,1);
var message = threads[0].getMessages()[0];
var attachment = message.getAttachments()[0];
// Is the attachment a CSV file
attachment.setContentTypeFromExtension();
if (attachment.getContentType() === "text/csv") {
var ss = SpreadsheetApp.getActive();
var sh = ss.getSheetByName("Streeterville Sales");
//parses content of csv to array
var dataString = attachment.getDataAsString();
var csvData = CSVToArray(dataString);
// Remember to clear the content of the sheet before importing new data
sh.clearContents().clearFormats();
//pastes array to sheet
var lastRowValue = sh.getLastRow();
for (var i = 0; i < csvData.length; i++) {
sh.getRange(i+lastRowValue+1, 1, 1, csvData[i].length).setValues(new Array(csvData[i]));
}
if( message.getSubject().indexOf('END OF DAY SALES DETAILS') !== -1) {
STlogTodaysSales()
}
//marks the Gmail message as read, unstars it and deletes it using Gmail API (Filter sets a star)
message.markRead();
message.unstar();
Gmail.Users.Messages.remove("me", message.getId()); // Added
}
}
//The code formats the code so it can be entered into the Google Script
function CSVToArray( strData, strDelimiter ){
// Check to see if the delimiter is defined. If not,
// then default to comma.
strDelimiter = (strDelimiter || ",");

(

// Quoted fields.

Your problem is due to threads being empty.
What you can do to avoid this error is, before trying to use a property of threadscheck if it's !=null.
Add a check like this: if (threads && threads.length>0) before continuing.
