Errors in Lambda for the Config Visualization Automation

[mstama]

I'm testing the sample automation available here:
https://github.com/aws-samples/aws-management-and-governance-samples/tree/master/AWSConfig/AWS-Config-Visualization

And notice some errors in the Lambda provisioned:

• Pattern in the Lambda does not support prefix.
  The central Config bucket provisioned by Control Tower uses a prefix and the pattern used in the automation (and in the original blog post) does not support it.
  The code has this:

  return re.match('^AWSLogs/(\d+)/Config/([\w-]+)/(\d+)/(\d+)/(\d+)/ConfigSnapshot/[^\\\]+$', object_key)

  It should be like this:

  return re.match('.*/AWSLogs/(\d+)/Config/([\w-]+)/(\d+)/(\d+)/(\d+)/ConfigSnapshot/[^\\\]+$', object_key)

• Wrong group selected for region.
  After the match the function to retrieve the region has the wrong match group returned.
  The code has this, that is the account:

  def get_configuration_snapshot_region(match):
    return match.group(1)

  It should be like this:

  def get_configuration_snapshot_region(match):
    return match.group(2)

Also the blog post mentions that the timeout of the Lambda Function should be changed to 1 min due to the partition creation but the automation keeps the default 3s.
