NodeJS inspector - evaluate with throwOnSideEffect and replMode returns nothing

Question

Node: v16.13.1 under OS: macos 12.2 (Darwin Kernel Version 21.3.0)

Under the following circumstance, the evaluate method when used with replMode and throwOnSideEffect parameters does not do anything. The same method works perfectly when throwOnSideEffect and replMode are set separately, or when a different expression is provided (such as 1+1). Evaluating a non existing variable seems not being appealing to NodeJS. I am expecting an ReferenceError result but instead the process just returns 0.

I am using the function wrong or I missed something... ?

const inspector = require('inspector');

const session = new inspector.Session();
session.connect();

function myEval(expression, throwOnSideEffect, timeout, replMode) {
    session.post(
        'Runtime.evaluate',
        { expression, throwOnSideEffect, timeout, replMode },
        (err, res) => {
            if (err) {
                return console.error('err');
            }
            return console.log('works', res);
        });
}

// does not work as expected when executed alone
myEval('doesNotExist', true, 200, true);

// works as expected
// myEval(exp, true, 200, false);

// works as expected
// myEval(exp, false, 200, true);

Upgrading node to the version v17.7.2 resolved the problem.
