Google Pub/Sub - No event data found from local function after published message to topic - python-3.x

Question

I'm using the Functions Framework with Python alongside Google Cloud Pub/Sub Emulator. I'm having issues with an event triggered from a published message to a topic, where there's no event data found for the function. See more details below.
Start Pub/Sub Emulator under http://localhost:8085 and project_id is local-test.
Spin up function with signature-type: http under http://localhost:8006.
Given a background cloud function with signature-type: event:
Topic is created as test-topic
Function is spinned up under http://localhost:8007.
Create push subscription test-subscription for test-topic for endpoint: http://localhost:8007
When I publish a message to test-topic from http://localhost:8006 via POST request in Postman, I get back a 200 response to confirm the message was published successfully. The function representing http://localhost:8007 gets executed as an event as shown in the logs from the functions-framework. However, there's no actual data for event when debugging the triggered function.
Has anyone encountered this? Any ideas/suggestions on this?Perhaps, this is true? #23 Functions Framework does not work with the Pub/Sub emulator

I'll close this post, since the issue is an actual bug that was reported last year.
Update: As a workaround until this bug is fixed, I copied the code below locally to functions_framework/__init__.py within view_func nested function, inside _event_view_func_wrapper function.
if 'message' in event_data:
if 'data' not in event_data:
message = event_data['message']
event_data['data'] = {
'data': message.get('data'),
'attributes': message.get('attributes')
}
