SyntaxError: Unexpected token class (line 421, file "Code", project "GmailUtils")

[pony-bliberatore]

Trying your sample code. Added both libraries, and then added this code.

function saveExpenses() { GmailUtils.processStarred('label:Accounting_PDF', 5, function(message) {

// create a pdf of the message
var pdf = GmailUtils.messageToPdf(message);

// prefix the pdf filename with a date string
pdf.setName(GmailUtils.formatDate(message, 'yyyyMMdd - ') + pdf.getName());

// save the converted file to the 'Expenses' folder within Google Drive
DriveUtils.getFolder('Accounting_PDF').createFile(pdf);

// signal that we are done with this email and it will be marked as read
return true;

}); }

Upon run, I receive this error: SyntaxError: Unexpected token class (line 421, file "Code", project "GmailUtils")

Using version 4 of the GmailUtils and version 1 of the DriveUtils.

I see a similar error if I turn on the new apps script runtime in GAS: "Future executions of this project will run with Apps Script V8. Disable anytime via the Run menu." Solved by turning that off, but I think long term we need to resolve the issue. Does anyone know how to solve it?

[lex3001]

I can't see how to create a branch to contribute here, but below is my updated code with two fixes for Apps Script V8:
