Unexpected Warnings from FilterTable::ExceptionCatcher

[dwmarshall]

Running inspec on a profile produces numerous warnings. They seem not to affect the operation, however.

Describe the problem

I haven't been able to narrow this down to a particularly small example, but I wanted to create the issue in the hope that someone with greater wisdom will recognize the problem before I do much more work on it.

This output is from a Mac running a centos/7 Vagrant instance with

Chef Workstation version: 20.12.205
Chef Infra Client version: 16.8.14
Chef InSpec version: 4.24.8
Chef CLI version: 3.0.33
Chef Habitat version: 1.6.181
Test Kitchen version: 2.8.0
Cookstyle version: 7.3.11

When I run inspec exec https://github.com/dev-sec/cis-dil-benchmark.git --backend ssh --host default --user vagrant -p 2222 --key-files ~/.vagrant/machines/default/virtualbox/private_key 2>&1 I get lots of output warnings.

Here are the first few lines, and the full output I got is attached.
