unexpected error error="undefined method `router=' for #<Fluent::Plugin::StdoutOutput:…>

[martin21]

Masa told me:

This is a bug of out_copy and non-emittable output combination, e.g.
out_stdout. v0.14.1 will fix this problem.

As per his request I open an issue about it.

With

# gem list | grep fluent
fluent-mixin-config-placeholders (0.4.0)
fluent-plugin-elasticsearch (1.5.0)
fluent-plugin-parser (0.6.1)
fluent-plugin-secure-forward (0.4.1)
fluent-plugin-snmptrap (0.0.1)
fluentd (0.14.0, 0.12.24)
fluentd-ui (0.4.3)

and

<match *.**>
  @type copy
  <store>
    @type elasticsearch
    host localhost
    port 9200
    include_tag_key true
    tag_key @log_name
    logstash_format true
    flush_interval 10s
  </store>
  <store>
    @type stdout
  </store>
</match>

I get
