JS:

const url = 'http://local-folder.lambdatest.com/icu.html';
const url2 = 'https://google.com/ncr';

module.exports = {

    'test1': (browser) => {
        browser
            .url(url)
            .waitForElementVisible('body', 10000)
            .assert.title('Page Title')
            .execute(function(arg) {
                document.getElementById("results").innerHTML = arg;
                return arg;
            }, [123], function(res) {
                console.log(res);
                browser.assert.equal(res.value, "123");
            })
            .end();
    },
    'test2': (browser) => {
        browser
            .url(url2)
            .waitForElementVisible('body', 10000)
            .execute(function(arg) {
                document.querySelector('input[type=text]').value = arg;
                return arg;
            }, [123], function(res) {
                console.log(res);
                browser.assert.equal(res.value, "123");
            })
            .end();
    },

    afterEach: function(client, done) {
        setTimeout(function() {
            done();
        }, 1000);
    }
};

HTML for test1:

<!DOCTYPE html>
<html>
<head>
    <meta charset="utf-8" />
    <meta http-equiv="X-UA-Compatible" content="IE=edge">
    <title>Page Title</title>
    <meta name="viewport" content="width=device-width, initial-scale=1">
</head>
<body style="background-color: aliceblue;">
    <div>
        <h1>T</h1>
    </div>
    <div id="results"></div>
</body>
</html>

Output

Nightwatch-cli output:

...

But in LambdaTest Dashboard at Automation section i got expected result:

Same with 'test2

If i running nightwatch test with my local hub on selenium-server-standalone-3.141.5.jar - there is no errors.
I think your selenium hub does not return result value to my nightwatch, cuz i see right result value in dashboard (screenshot above).
Can you help me?

upd. I work with ssh tunnel. so i tried to run nightwatch with "tunnel: false" - same error

Some another execute method errors

test.js (modified version of 'test2' testcase)

const url2 = 'https://google.com/ncr';

module.exports = {
    'test2': (browser) => {
        browser
            .url(url2)
            .assert.title('Google')
            .execute(function(arg) {
                document.querySelector('input[type=text]').value = arg;
                return arg;
            }, [123], function(res) {
                console.log('response:\n', res);
                browser.assert.equal(res.value, "123");
            })
            .end();
    },

    afterEach: function(client, done) {
        setTimeout(function() {
            done();
        }, 1000);
    }
};

nightwatch envs (without tunnel)

        "firefox": {
            "desiredCapabilities": {
                "platform": "Windows 10",
                "browserName": "Firefox",
                "version": "64.0"
            }
        },

        "edge": {

                "version": "10.0"
            }
