Catch all errors

[Aaron Weiner]

Hello, 

I have a semi-complex script that I have created and it has worked perfectly for months. 

It's using the executeInParallel function to process multiple accounts at the same time. 

Recently, I noticed that it was throwing an error when I reviewed the logs. 

I have since fixed the problem which was a mistake on my part.

That said, what's the best way for setting up a catch all type of error reporting across this entire script?

Thanks

Hi Aaron,

You could set-up a try-catch logic in your script and have the script email you if any errors have been encountered during the execution. You could also write the error information to a spreadsheet doc using the SpreadsheetApp class and then email a link to this document.

Below is a sample code snippet:

function main() {
   try {
    //Insert your script logic here
  } catch(e) {
    //Catch any error here. Example below is just sending an email with the error.
    MailApp.sendEmail('INSERT_EMAIL_ADDRESS_HERE',
                    'Sample Script - Error',
                    e);
  }
}

Let me know if you have further clarifications.

Thanks,

Hello Vincent,

Take this code example that you guys have - https://developers.google.com/adwords/scripts/docs/features/mcc#working_on_accounts_in_parallel

Would I need the try and catch in the main, processClientAccount, and afterProcessAllClientAccounts functions?

Or would adding it to just the main function be sufficient? 

Thanks and I look forward to your reply.

Hi Aaron,

The scenario for catching errors in an MCC level script which runs in parallel is different. Since the methods in executeInParallel are considered independent methods, then you need to put a try-catch logic in main(), processClientAccount() and afterProcessAllClientAccounts() functions. However, you can have a global variable which contains all the exception messages if there are any errors on these functions. And then, on the last part of the script's execution (before the main() function ends), you can send an email if the global variable is not empty.

Thank you very much.
