Hi team, After restart the growthbook docker service, I can no longer track the experiment. I expect to reach

on_experiment_viewed

with printed lines when I run gb.get_feature_value. However the only result is True/False. Here is the dummy python code:

from growthbook import GrowthBook

# User attributes for targeting and experimentation
attributes = {'user_id': 'xxxx'}

def on_experiment_viewed(experiment, result):
  # TODO: Use your real analytics tracking system
  print("Viewed Experiment")
  print("Experiment Id: " + experiment.key)
  print("Variation Id: " + result.key)

# Create a GrowthBook instance
gb = GrowthBook(
  on_experiment_viewed = on_experiment_viewed,
  api_host = "<http://xxxxxxxxx>",
  client_key = "sdk-xxxxxxx"
)

>>> gb.set_attributes(attributes)

# Load features from the GrowthBook API with caching
>>> gb.load_features()

# Simple on/off feature gating
>>> gb.is_on("exp_id")
True

# Get the value of a feature with a fallback
>>> gb.get_feature_value("exp_id", "fallback")
True

you should check to see what the feature payload is

Thanks Graham! Could you please be more specify? I donot see "feature payload" tab.

if you go to the SDK page

the full API endpoint url do return a payload
