InputError: Unrecognized function name "main"

[Jay Wilner]

Beginner here. Wondering what this error means: InputError: Unrecognized function name "main".  Just trying to run this example script: https://developers.google.com/google-ads/scripts/docs/examples/reports?hl=en#create-a-text-report

I am assuming this script is somehow calling a function named "main"? I just cut and pasted the code provided.

thanks in advance!

Hello Jay,

Thank you for providing the requested information. I checked your script and I observed that you’re not utilizing the function main() which is the main reason why you encountered the said error. Having said that, I made some adjustments to your script below for it to work on your end.

function main() {
  const searchResults = AdsApp.search(
      'SELECT campaign.name, metrics.clicks, metrics.impressions, metrics.cost_micros ' +
      'FROM   campaign ' +
      'WHERE  metrics.impressions < 10 ' +
      ' AND   segments.date DURING LAST_30_DAYS');

  for (const row of searchResults) {
    const campaignName = row.campaign.name;
    const clicks = row.metrics.clicks;
    const impressions = row.metrics.impressions;
    const cost = row.metrics.cost;
    console.log(`${campaignName}, ${clicks}, ${impressions}, ${cost}`);
  }
}

Can you please try to implement the given code above and let me know how it goes on your end?

Hi Jay,

most probably you have copy-pasted the code from the example you mentioned in the Google Ads scripts editor, and removed the initial main() function that is required.

The main() function is the function that gets executed first when a script is run.

You can fix this by adding the following at the top of your script:

function main() {

  runReport();

}

This will call the runReport function from within the main function.
