[Bug]: Complex regex issue on node definition

[ltning]

Is this a critical security issue?

• This is not a security issue.

Describe the Bug

This is the same issue as in the (old) Puppetlabs server:
puppetlabs/puppet#9483

Basically, our moderately complex node definition regexes fail with current openvox-server, for example:
node /^(db01)\.(?!hosts).*$/ {

The match fails in a way that simply causes the node not to be found.

A patch exists; see below.

Expected Behavior

The node should be found.

Steps to Reproduce

Use a complex regex to match node names, possibly with negative lookaheads.

Environment

Version openvox-server8-8.12.1_1, openvox-agent8-8.25.0
Platform FreeBSD 15

NOTE: While the file in question is from the agent, the problem only manifests and only needs to be patched on the server instance.

NOTE 2: An issue since puppetserver 8.x and in all versions of openvox-server/agent.
