Please don't mark this question as a duplicate, because the other solution doesn't work for me.

I'm using Angular v5.x and using Protractor for E2E testing. But on running the command.

ng e2e -s false

It is throwing an error as

 Failed: unknown error: call function result missing 'value'
  (Session info: chrome=71.0.3578.98)
  (Driver info: chromedriver=2.24.417431 (9aea000394714d2fbb20850021f6204f2256b9cf),platform=Windows NT 10.0.17134 x86_64)

I've followed this issue on GitHub, but no luck!!! I've also install latest chrome driver from this link http://chromedriver.chromium.org/downloads. After unzipping and executing the .exe file a console window opens, prompting this message

Starting ChromeDriver 2.45.615291 (ec3682e3c9061c10f26ea9e5cdcf3c53f3f74387) on port 9515 Only local connections are allowed.

I've re-run the same command again but not working. I've also checked using chromedriver --version the version of chromedriver it is v2.45.

Chrome version - 71.0 Chrome drivers version - 2.45

  • The log message that you have share which is before updated chromedriver of after that ? – akshay patil Jan 17 '19 at 07:44
  • @akshaypatil It's after the update – Yashwardhan Pauranik Jan 17 '19 at 08:01
  • @YashwardhanPauranik did you resolve this issue? I have tried other solutions that are mentioned but it doesn't work for me. Thanks in advance. – Alfredo Bazo Lopez Aug 05 '20 at 06:36
  • @AlfredoBazoLopez Non of the below solution worked for me. What I did is, I have updated my project from Angular `v5.x` to the latest `v7.x` (at that time). – Yashwardhan Pauranik Aug 05 '20 at 08:24
  • Thanks, @YashwardhanPauranik and did this work for you? I cannot do it because I am the QA and not the developer of the project. I am getting mad because non of the solutions provided in internet works for me. I am testing it in a real device and although I am using chromedriver 84, it seems that it is taking an old version: WebDriverError: unknown error: call function result missing 'value' (Session info: chrome=84.0.4147.111) (Driver info: chromedriver=2.28.455517 – Alfredo Bazo Lopez Aug 05 '20 at 09:19
  • @AlfredoBazoLopez I totally understand your problem. There is some sort of issue in the WebDriver. I would recommend to ask them to use latest version of Angular for better support. – Yashwardhan Pauranik Aug 05 '20 at 10:53

As per the error message, it suggest that call to webdriver(wire protocol) responded empty. I suggest downgrade to your chrome to any stable version below 70 and compatible chromedrive.

As you share console message :-

Starting ChromeDriver 2.45.615291 (ec3682e3c9061c10f26ea9e5cdcf3c53f3f74387) on port 9515 Only local connections are allowed.

this is information message in console in red color, you can avoid and after this you chrome session means chrome window turn on and if you pass any URL it will redirect to that if you have error after this please share with us because i doesn't seem any problem

  • @Akshay Patil. Your language is confusing me. I'm not able to get what you are suggesting – Yashwardhan Pauranik Jan 17 '19 at 08:06
  • @DebanjanB Also, the solution you are pointing to, has the last comment that "This solution doesn't work with `v71.x`". Check https://stackoverflow.com/a/48665237/5893995 – Yashwardhan Pauranik Jan 17 '19 at 08:11
  • @YashwardhanPauranik You need to update the question and demonstrate how your question is different from the dup marked question. For the record, the most upvoted answer within the dup marked discussion have **107** upvotes and a detailed explanation within the second most upvoted answer. – undetected Selenium Jan 17 '19 at 08:17
  • @DebanjanB But that solution not fixing the problem for latest chrome version and that is how this question is a bit different – Yashwardhan Pauranik Jan 17 '19 at 08:19
