Jmeter WebDriver Sampler resulting in 'unknown protocol: data'

Question

I am currently trying to put load on HTTPS website by using Webdriver Sampler in Jmeter. Jmeter successfully runs the whole Selenium code in Webdriver Sampler; but in the end, marks the sampler as Failed in 'View Results Tree' listener. Response data > Response Body shows

java.net.MalformedURLException: unknown protocol: data

It's strange, as it already has executed the whole code successfully with even closing the browser. What's the point of giving this error in the end?

What is the way out to avoid this failure?

Answer 1

The error means that you open the browser and don't call WebDriver.get() function

Please inspect all your WebDriver Samplers and ensure that there is the following call in each of them:

WDS.browser.get('https://example.com')

replace example.com with the URL of the application you're testing.
