NoMethodError

[egkelly]

What happened:
My logs weren't showing up in Splunk, so I dug a little deeper in the fluentd logs and found this throw during the output process:
[warn]: #0 got unrecoverable error in primary and no secondary error_class=NoMethodError error="undefined method `request_uri' for #<URI::Generic >

What you expected to happen:
My logs arrive in splunk under my specified index

How to reproduce it (as minimally and precisely as possible):
Here is my output config:

  @type splunk_hec
      hec_host http-inputs-firehose.mycompany-com.splunkcloud.com
      hec_port 8088
      protocol https
      hec_token XXXXXXXXXX
      index aws-kinesis-firehose-generic
      <buffer tag, time>
        @type memory
        timekey 60
      </buffer>

I am running version 1.3
