superclass mismatch for class Uniquefile (TypeError)

Puppet Version: puppet-agent-7.7.0-1.fc32.x86_64
Puppet Server Version: 6.12.1 (Helm Chart: 5.1.0)
OS Name/Version: Fedora 34

After the puppet-agent update from puppet-agent-7.6.1-1.fc32.x86_64 to
puppet-agent-7.7.0-1.fc32.x86_64  the agent seems to fail.

I have observed this on multiple machines. A rollback to 7.6.1 fixes the issue.

I've tried the nightly builds for fedora 34 and they give the same output as below.

Desired Behavior: Retrieves the client configuration from the Puppetserver and applies it to the local host.

Actual Behavior:

If I run the following: /opt/puppetlabs/bin/puppet agent -t --verbose --certname $(hostname -s) --vardir /var/.puppetcache --debug --trace

A tcpdump and the logs indicate that the Puppetserver was never contacted.
I can't really make sense of the output.

Let me know if you need any more information.
