Expected Behavior

The samples should work as expected. All dependencies needed should be in requirements.txt.

Actual Behavior

The requirements.txt files do not include the cloudevents package. This results in:

Traceback (most recent call last):
  File "json_sample_server.py", line 16, in <module>
    from cloudevents.http import from_http
ModuleNotFoundError: No module named 'cloudevents'
