Log full exception on the client side from Google Apps Script back end

Question

I am trying to debug an add on which has been published, however the exception I get back from the GAS back end does not give me much information other than the line and function it was thrown from.

Is there a way to get a more detailed error description passed back to the client?

In my example I am calling the function testException, all it currently does is throw an exception.

CLIENT SIDE CODE

google.script.run
    .withSuccessHandler(result => console.log(result))
    .withFailureHandler(error => console.error(error))
    .testException();

SERVER SIDE CODE

function testException() {
    throw new Error('Test message to show on client side');
}

All the information I get back is the following:

at testException (code:196) (Test Add On) 42bb9613-6241-4ab9-b39f-01fe5c56b060

If possible I would like to get the same level of detail as the stackdriver logging. Or even just the error message 'Test message to show on client side'.

You can access the message inside the js error object using:

console.error(error.message)
