[Possible BUG] MJSONWP protocol requires type and ms" and you sent {"script": 1000}

[raquelgs]

Hello,

What are you trying to achieve?

I'm using Codeceptjs with webdriverio and browserstack (automate) and I’m facing an issue related with MJSONWP endpoint to fetch the timeouts and makes my test suite to crash.

What do you get instead?

Error: Parameters were incorrect. We wanted "MJSONWP protocol requires type and ms" and you sent {"script":1000}

-- FAILURES:

  1) Commit valid answer
       "before each" hook: codeceptjs.before for "Commit a valid answer for an explicit commit block":
     Parameters were incorrect. We wanted "MJSONWP protocol requires type and ms" and you sent {"script":1000}
  rror: Parameters were incorrect. We wanted "MJSONWP protocol requires type and ms" and you sent {"script":1000}

Details

• CodeceptJS version: 2.0.4

• NodeJS Version: 10

• Operating System: Mac OS 10.13

• WebDriverIO 5.6.3

• Using inside browserstack: appium_version: 1.9.1 (Tried with 1.6.5, 1.7.1, etc...)**

• Configuration file:
  What I found interesting is that Inside my config file (codeceptjs config file) I do not specify any timeout option.

exports.config = {
  tests: './test_codecept/*.js',
  output: './test_codecept/output',
  helpers: {
    WebDriver: {
      host: 'hub.browserstack.com',
      path: '/wd/hub',
      url: 'http://WEBSITE:8080/renderer',
      user: 'xx',
      key: 'xx',
      browser: 'iphone',
      desiredCapabilities: {
        'os_version' : '11',
        'device' : 'iPhone 8',
        'real_mobile' : 'true',
        'browserstack.local' : 'true',
        'browserstack.debug' : 'true',
        'browserstack.networkLogs' : 'true',
        'browserstack.appium_version' : '1.9.1',
        'browserstack.user' : 'xx',
        'browserstack.key' : 'xx'
      }
    }
  }
}

After failing a few times, I tried to specify a timeout option inside the helper like mention in the w3c WebDriver spec
and didn't work neither, appeared that I was sending an empty object to the sessionId/timeouts.

timeouts: {
  type: 'script',
  ms: 1000
}

After that I tried to setup the timeouts like the error message propose: "type" and "ms", didn't work neither.

timeouts: {
  type: 'script',
  ms: 1000
}

Thanks for reading

Codecept with WebDriver/WebDriverIO/Appium calls defineTimeout after browser starts.
I think, problem in "browser" field. What it you fill it as "safari" ?

Maybe, it's WebDriverIO issue.

[raquelgs]

@LukoyanovE I tried both options for browser. Interesting is that running tests on Android (same Appium version) works.

I opened an issue on WebdriverIO but they indicated it was a Codeceptjs issue.

[elukoyanov]

@raquelgs, which two options did you use?

Can You place config for android, if it works?

[raquelgs]

exports.config = {
  tests: './test_codecept/*.js',
  output: './test_codecept/output',
  helpers: {
    WebDriver: {
      host: 'hub.browserstack.com',
      path: '/wd/hub',
      url: process.env.URL,
      user: 'SECRET_USER',
      key: 'SECRET_KEY',
      browser: 'DOESNOTMATTER', // Here we can specify anything, because it's ignored once you are running in BrowserStack.
      desiredCapabilities: {
        os_version: '7.0',
        device: 'Samsung Galaxy S8',
        real_mobile: 'true',
        'browserstack.local': 'true',
        'browserstack.debug': 'true',
        'browserstack.networkLogs': 'true',
        'browserstack.appium_version': '1.9.1'
      }
    }
  }
}

This is the request for Android:

@LukoyanovE I've been checking with webdriverio 4.14.1 and same test on iOS works. Here the traces:

[HTTP]

[raquelgs]

@LukoyanovE Do you have any update? Thanks!

[vigneshshanmugam]

Seems like a bug in appium - appium/ruby_lib_core#128, But the fix itself has landed in 1.9.1 and still the issue exists. Worth a try with the new appium release.

[lokesh-rj]

Hi, Is this issue resolved?

[raquelgs]

@lokesh-rj I still need to try with appium latest release. Without having investigated more, using same appiume version (1.9.1) with webdriverio 4 it was working fine

[danieltisdale]

@lokesh-rj @raquelgs any updates on this? We are using Sauce Labs and I reached out to their support team and they seemed to say the same thing that it was a bug in CodeceptJS.

[raquelgs]

@danieltisdale I was not able to try with a version higher than 1.9.1 (no device available with this version, I've contacted Browserstack support team)

[nagamanickamm]

@raquelgs : is this issue resolved?
I'm facing the same issue in IOS devices, but the same code is working in Android.

[pablopaul]

I have the same problem.

@raquelgs what does the BrowserStack support answered, could they help you to fix it?

[raquelgs]

@pablopaul copy&paste of their response:
To execute the tests on iOS, XCUITest driver is used, however, to execute the tests on Android, Appium Driver is used. From the Appium Logs, I observed that the client bindings at your end are sending the request in W3C mode, however, WebdriverIO understands the request in W3C mode, only when Appium Driver is used. Hence setting timeouts is being executed successfully on Android since to execute tests on Android, Appium driver is used and to execute tests on iOS, XCUItest Driver is used. Hence, using WebdriverIO, you are able to set the timeouts when running the test on Android device, whereas setting the timeouts on an iOS device, throws the error 'Error: Parameters were incorrect. We wanted "MJSONWP protocol requires type and ms" and you sent {"script":1000}'.

[pablopaul]

thanks @raquelgs I am confused now :)
