Retry try catch in Google Apps Script

When processing results of Google forms with Google Apps Script accessing the form by …

    let formID = FormApp.getActiveForm().getId();

… sometimes fails with an exception like "Form data could not be retrieved." Manually started just a minute later it works properly.

To handle those errors the best way I want to catch the exception and retry the method one minute later. I came up with this:

    function foo() {
      const maxTries = 3;
      let formID;
      let tries = 1;
      while(true) {
        try {
          formID = FormApp.getActiveForm().getId();
          break;
        } catch (e) {
          console.log("Retrieving form data failed (" + tries + ")");
          if (tries >= maxTries) {
            console.log("Retrieving form data not possible"); // and/or …
            throw(e);
            return;
          } else {
            tries++;
          };
        };
      };
      // Do things with form stuff
    };

How can I insert a 60 second pause between the tries? And I'm not sure anyway, if there isn't a better way to overcome those errors (at all or within Google Apps Script).

In this case why don't you try using Utilities.sleep. This method will pretty much puts the script to sleep for a set amount of time. Please note the maximum amount is of 5 minutes as the maximum execution time for a script is of 6 minutes. You can check runtime limits in the documentation.
