In this podcast, we’ve explored issues with file uploads in headless Selenium after logging in using hasAuthentication selenium. We learned that the 422 HTTP error during file uploads often occurs because authentication headers are attached to the file upload request, which the server doesn’t expect. To solve this, we can use separate WebDriver instances for login and file upload, utilize a REST API for uploads, or switch to tools like Playwright. Listen to this to know more about these methods to make your headless tests more reliable.
