Reproduce the screenshot request after upgrading to version 0.5.0, using the Android endpoint shown in the logs. Trace uiautodev/router/device.py, driver/android.py, and uiautomator2/__init__.py through the screenshot call and inspect why the base64 input is None. Done means the screenshot request succeeds instead of returning HTTP 500, with a regression test or verified reproduction if the repository provides one.
