How to properly handle Google SDK errors in Google App Script - debugging

Question

I am writing a google web app which uses the Admin Directory a lot. However I was wondering how the error handling should be done since I do not get a proper error object back when a request to the api fails.
Example: I want to check if a custom schema exists and if not I want to do something else:
try{
var resp = AdminDirectory.Schemas.get("129898rgv", "someCustomSchema");
}catch(err){
// if schema does not exist do this
schemaNotExistFunction();
Logger.log(err);
}
Unfortunately I do not even get the http status code back from the err. Is there another way to handle errors in Google Apps Script?

Instead of
Logger.log(error)
use
Logger.log('%s, %s',error.message, error.stack);
See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Error for a complete list of Error instance properties
The above because Logger.log parses the parameter as string. When you pass an error object error.name is logged, by the other hand by using
Example
Running the following code in an standalone project using the new runtime (V8) will log a couple of messages.
function myFunction() {
try{
SpreadsheetApp.getUi();
} catch (error) {
Logger.log(error);
Logger.log('%s, %s', error.message, error.stack);
}
}
Another alternative is to use console.log instead of Logger.log
function myFunction() {
try{
SpreadsheetApp.getUi();
} catch (error) {
console.log(error);
console.log('%s, %s', error.message, error.stack);
}
}
