		// As of Puppeteer 1.6.1, `message.text()` wrongly returns an object of
		// type JSHandle for error logging, instead of the expected string.
		//
		// See: https://github.com/GoogleChrome/puppeteer/issues/3397
		//
		// The recommendation there to asynchronously resolve the error value
		// upon a console event may be prone to a race condition with the test
		// completion, leaving a possibility of an error not being surfaced
		// correctly. Instead, the logic here synchronously inspects the
		// internal object shape of the JSHandle to find the error text. If it
		// cannot be found, the default text value is used instead.
