Please file safaridriver bugs to https://bugreport.apple.com/ Additionally, you have not provided any useful information, so I can't help you. Perhaps include the following: Is this behavior reproducible in Safari Technology Preview (STP)? https://developer.apple.com/safari/technology-preview/ Include versions of Selenium or other WebDriver client libraries, Safari, safaridriver, macOS. Describe the failing command and its inputs and outputs. Did this behavior occur in a previous release of Safari? Does this behavior occur in other browsers (Firefox, Chrome, Edge)? What language is the test written in? Do you use Selenium Grid, SauceLabs, BrowserStack, or other scaling infrastructure? If possible include a Webarchive of the page as it was when the command failed, a test page accessible to Apple engineers, and the test case itself.
