Unable to start WebDriverAgent session: An unknown server-side error occurred while processing the command. Original error: Failed to launch com.apple.mobilesafari application - Appium1.6.3 -iOS 10.1

The problem

I am able to run a test but when the test finishes and breaks down I cannot run a second test. Appium gives the error “Unable to start WebDriverAgent session: An unknown server-side error occurred while processing the command. Original error: Failed to launch com.apple.mobilesafari application”

I am skeptical that the tear down for the webDriverAgent is working correctly.

This is the appium log when the test teardown begins:

Then appium tries to creates a new XCUITestDriver session and fails

Then it tries to launch WebDriverAgent on the device again, and again, and again… (in full appium logs)

@mollywhitnack just as an FYI, you shouldn’t need to specify the bundleId capability if you have browserName set to Safari, as you do here.
