@AutomatedTester why is it duplicate of https://github.com/SeleniumHQ/selenium/issues/3808?
My issue doesn't relate to grid.

Actually a duplicate of #3693

Not a duplicate. Did you just pick random issues out of a hat?

@jpope19 Do you have any reason to hijack an issue closed a year ago without providing any additional information?

I'm coming across the same issue as @zenonwch and read through the "related" issues and it ended up just being a waste of 20 minutes. I'm new to the node.js library for selenium. I'm submitting a form and testing the redirect to a new page. Any suggestions?

let email = await driver.findElement(By.id('email')).sendKeys('un'); let pw = await driver.findElement(By.id('pass')).sendKeys('pw'); let form = await driver.findElement(By.id('login_form')); await form.submit();

gives the following error:

{ UnknownCommandError: POST /session/2c5e7b2c-8f94-495e-b593-87ed223b771a/element/5c6fd2f7-c8e8-4a65-9bc4-6cbda6
