AttributeError: 'StatsDWrapper' object has no attribute '_get_aggregate_metrics_and_dists'

[g-farrow]

Expected Behavior

The lambda runs without error logs

Actual Behavior

DataDog Python code is throwing the following exception:

Traceback (most recent call last):
  File "/opt/python/lib/python3.8/site-packages/datadog_lambda/wrapper.py", line 180, in _after
    flush_thread_stats()
  File "/opt/python/lib/python3.8/site-packages/datadog_lambda/metric.py", line 100, in flush_thread_stats
    _, dists = lambda_stats._get_aggregate_metrics_and_dists(float("inf"))
AttributeError: 'StatsDWrapper' object has no attribute '_get_aggregate_metrics_and_dists'

Steps to Reproduce the Problem

1. Using the Datadog-Extension v7 and Datadog-Python38 v36 - also using AWS Lambda Powertools' Logger and Tracer
2. When the Lambda is invoked, the above exception is thrown immediately
3. The lambda code appears to then run correctly - however, its not clear if the DataDog stats and logs are gathered properly

Specifications

• Datadog Lambda Layer version: 36
• Python version: 3.8
• AWS Powertools Logger and Tracer (v1.15.0)

Hi @g-farrow. Thanks for the report. This looks like a recent regression with the python layer and our preview extension. I'm taking a look now, but I believe this change was introduced in v36. We're going to try and get a fix out for this as soon as possible.
