nightwatch: Errors when working with Firefox against selenium hub (only)

NW version: 1.1.14 Node version: v10.16.0 NPM version: 6.9.0 Firefox Version: 67.0 Gecko Driver: 0.24.0 Selenium Hub Version: 3.141.59

The errors not occurs when working directly against selenium node but only when working against selenium hub

you can see the first error when trying to navigate to url when the navigation results value is null (while in chrome the results are as expected see below code):

"simple test against selenium hub" : function(browser) {
      browser.url("https://nightwatchjs.org/", function(results){
        console.log("Nav Results: " + JSON.stringify(results));
      })
    }
// Nav Results: {"value":null} - firefox
// Nav Results: {"sessionId":"6b6a3b345d1a8206583e30eaa5e8b54b","status":0,"value":null} - chrome

here is the verbose log:

Request POST http://myhub:4444 /wd/hub/session
{ desiredCapabilities: { browserName: ‘firefox’, acceptSslCerts: true, platform: ‘ANY’, javascriptEnabled: true, acceptInsecureCerts: true, elementScrollBehavior: 1, name: ‘my test’ } } Response 200 POST http://myhub:4444/wd/hub/session (2910ms) { value: { sessionId: ‘541f6274-0025-4352-a06d-efc96608e8c5’, capabilities: { acceptInsecureCerts: true, browserName: ‘firefox’, browserVersion: ‘67.0.4’, ‘moz:accessibilityChecks’: false, ‘moz:buildID’: ‘20190619235627’, ‘moz:geckodriverVersion’: ‘0.24.0’, ‘moz:headless’: false, ‘moz:processID’: 1948, ‘moz:profile’: ‘C:\Users\qa\AppData\Local\Temp\rust_mozprofile.2Wz4QHdbjotc’, ‘moz:shutdownTimeout’: 60000, ‘moz:useNonSpecCompliantPointerOrigin’: false, ‘moz:webdriverClick’: true, pageLoadStrategy: ‘normal’, platformName: ‘windows’, platformVersion: ‘6.1’,

Another example is when try to execute js: - here i’m getting 'execute did not match a known command’ error

"simple test against selenium hub (js)" : function(browser) {
   browser.url("https://nightwatchjs.org/", function(results){
     console.log("Nav Results: " + JSON.stringify(results));
   });

   browser.execute(function(){
     console.log("browser log test")
   },[],function(results) {
     console.log("execute results: " + JSON.stringify(results))
   })
 }
// execute results: {"status":-1,"state":"","value":{"error":[],"message":"POST /session/be23eed8-73a2-40a2-bb21-8e4cf1b99966/execute did not match a known command"},"errorStatus":"","error":"POST /session/be23eed8-73a2-40a2-bb21-8e4cf1b99966/execute did not match a known command","httpStatusCode":404}
