Using Selenium and Pywinauto, file upload fails in headless mode because the system file dialog doesn’t appear. Are there alternative methods or workarounds for headless interactions?
Based on my experience when facing headless mode challenges, the system file dialog issues persist because headless environments often do not render native dialogs. One effective workaround involved directly assigning the file path to the hidden file input element via JavaScript, which bypassed the need to interact with the dialog. This method required ensuring that the element was accessible despite its hidden status. Adjusting wait times and using explicit waits also improved reliability, as it allowed for proper rendering and interaction before file selection operations occurred.
