Logstash-filter-fingerprint failing intermittently

Elastic Stack Logstash

My pipeline starts up fine and eventually fails for this error, and has only happened twice in a long period of time, but I would like to understand what is the issue.

Getting the following error:

Pipeline worker error,
 the pipeline will be stopped {:pipeline_id=>"main",
 :error=>"(NameError) uninitialized constant LogStash::Filters::Fingerprint::OpenSSL",
 :exception=>Java::OrgJrubyExceptions::NameError,

I'm assuming the offending line is this one line in the pipeine's configuration given the error message

                fingerprint {
                    concatenate_all_fields => true
                    target => "id"
                    key => "id-key"
                }

That is blowing up here. I cannot conceive of why that would intermittently fail. It should only get called when a new worker thread is created, which I thought only happens on startup.

@Badger sorry, I should clarify. This error does usually happen around the time of start up. The pipeline comes up initially and returns a 200, but then fails in the next 10-20 seconds. The intermittent part is that it doesn't always fail after start up. Most of the time, it's fine
