'Illegal characters in string' when updating custom parameters

[Matthew Debondt]

Hello

When I try to update the custom parameters (campaign & adgroup) on ad group level with the script below, I keep receiving the error for illegal characters in the strings. They don't contain any whitespace or special characters like ö,ü,ä anymore. I can see that the code is working as intended from the changes log - emptying the cp's first and then inserting the updated campaign and ad group names.

Thanks for your comments.

function main() {

  var adGroupIterator = AdsApp.adGroups()
    .withCondition("CampaignStatus = ENABLED")
    .get();
 
  while (adGroupIterator.hasNext()) {
    var adGroup = adGroupIterator.next();
    var urls = adGroup.urls();
    urls.setCustomParameters({adgroup_name: " ", campaign_name: " "}); // empty the existing custom URLs
    var gn = adGroup.getName().replace(/\s/g,'_').replace(/[ö]/g,'oe').replace(/[ü]/g,'ue').replace(/[ä]/g,'ae').replace(/^[\r\n]+|\.|[\r\n]+$/g, "");
    Logger.log("Ad group name gn variable: " + gn);
    var cn=adGroup.getCampaign().getName().replace(/\s/g,'_').replace(/[ö]/g,'oe').replace(/[ü]/g,'ue').replace(/[ä]/g,'ae').replace(/^[\r\n]+|\.|[\r\n]+$/g, "");
    Logger.log("campaign cn variable: " + cn);
    urls.setCustomParameters({adgroup_name: gn, campaign_name: cn}); // Set new custom parameters
   
  }
}
