What is malfunctioning?

When an AWS EC2 instance is launched with cloud-init as the user data method it encodes the data in a format Facter does not parse (i.e., not UTF-8), which causes the following error when running facter.

Traceback (most recent call last):

/opt/puppetlabs/puppet/lib/ruby/2.7.0/json/common.rb:286:in `to_json': source sequence is illegal/malformed utf-8 (JSON::GeneratorError)

What does success look like?

This can be corrected by creating /etc/puppetlabs/facter/facter.conf and adding a block for the ec2_userdata fact.

facts : {

  blocklist : [ "ec2_userdata"]

How will success be validated?

facter should detect whether the ec2_userdata fact is encoded properly before attempting to add it to the facts hash.
