When the response of lambda contain data of type Decimal, datadog raise except TypeError: 'decimal.Decimal' object is not iterable

[jairoandrescastaneda]

Expected Behavior

When return response from DynamoDB and DynamoDB contains data of type Decimal

Actual Behavior

Get data of DynamoDB that contains data of type Decimal and raise next exception except TypeError: 'decimal.Decimal' object is not iterable And the trace and log data is not sent complete.

Steps to Reproduce the Problem

1. Get data from Dynamodb inside handler and return response.

In the code core de datadog_lambda in the line 37 raises of exception because Decimal is instance of object, but this is not iterable

  if isinstance(obj, object):
      for k in obj:
          v = obj.get(k)
          formatted_key = "{}.{}".format(key, k)
          tag_object(span, formatted_key, v, depth)
      return

Specifications

• Datadog Lambda Layer version:

• Python version: 3.8
