Per my emails of a couple of days ago, I have Decanter installed and it seems
to be working OK but I'm seeing the following in the log. I'm a bit confused
with what it might be trying to tell me. The Decanter::Collect::Log bundle is
installed and active as is the ElasticSearch appender. At first blush it
appears to only happen from a single log statement that is issued from within
an Exception handler block. I have a feeling I'm misunderstanding Decanter in
some way, any insight would be appreciated.
