Example is not running

[JochenKoehler69]

As stated in #9 I cloned this project and tried to execute it (build the app) after exchanging the line:
- name: Build with Buildozer
uses: ./master # REPLACE WITH ArtemSBulgakov/buildozer-action@v1

into
- name: Build with Buildozer
uses: ArtemSBulgakov/buildozer-action@v1

But I got a failure during the build:
[WARNING]: ERROR: /github/workspace/master/test_app/.buildozer/android/platform/build-armeabi-v7a/build/other_builds/hostpython3/desktop/hostpython3/native-build/python3 failed!

Command failed: ['/bin/python3', '-m', 'pythonforandroid.toolchain', 'create', '--dist_name=testapp', '--bootstrap=sdl2', '--requirements=python3,kivy', '--arch=armeabi-v7a', '--copy-libs', '--color=always', '--storage-dir=/github/workspace/master/test_app/.buildozer/android/platform/build-armeabi-v7a', '--ndk-api=21', '--ignore-setup-py', '--debug']

Is it possible, that the docker container is not working properly (anymore).
