[andrewkroh]

What does this PR do?

This fixes two errors observed while parsing data from CrowdStrike FDR.

Processor 'convert' with tag '' failed with message '192.168.1.129 192.168.1.35' is not an IP string literal.
Processor 'conditional' with tag 'process-uptime' failed with message cannot implicitly cast def [int] to java.lang.String
