'_LambdaDecorator' object has no attribute 'trigger_tags'

[CatalinAndrei-Flam]

Expected Behavior

Datadog should not throw errors, in previous version this did not happen. (extension_layer_version:64, python_layer_version:98)

Actual Behavior

Datadog throws errors because it cannot extract the tags from the event. In this case the incoming event is not a dictionary but a list of dictionaries that's generated by a dynamodb stream in an aws eventbridge pipe with batching enabling.

Steps to Reproduce the Problem

1. Update extension_layer_version to 65 and python_layer_version to 99
2. Create. eventbridge pipe with dynamodb stream to lambda and batching enabled .
3. Trigger multiple changes in the dynamodb table with stream enabled which will generate a list of dicts as an input event for the lambda that's failing.

Specifications

• extension_layer_version": 65
• python_layer_version: 99
• Python version: 3.11
