PR Summary
This PR improves argument handling in the fallbackLocatorMethod to support non-string arguments like file buffers in Playwright locator methods.
- Modified
lib/handlers/handlerUtils/actHandlerUtils.tsto remove automatic string conversion of arguments in fallbackLocatorMethod - Added type safety using TypeScript's Parameters utility type for locator method calls
- Created new
evals/tasks/upload_file.tsto test file upload functionality with base64-encoded PNG - Added 'upload_file' task entry in
evals/evals.config.jsonto validate the changes

style: Directly modifying observation.arguments could be fragile if the observation structure changes. Consider using a more robust pattern for setting upload parameters.

why
Handlers on locators (like Playwright's
setInputFiles) can accept non-string arguments, but the fallback logic for Stagehand acts stringifies arguments before they get passed to the underlying handlers.what changed
This avoids stringifying arguments before passing them to the underlying locator method.
