customfields configuration error/ignored?

Documentation example, produce com.fasterxml.jackson.core.JsonParseException:

<customFields>{"appname":"myWebservice","roles":["customerorder","auth"],"buildinfo":{"version":"Version 0.1.0-SNAPSHOT","lastcommit":"75473700d5befa953c45f630c6d9105413c16fe1"}}</customFields> the following josn will be excepted but will not appear in output: "appname":"myWebservice","roles":["customerorder","auth"],"buildinfo":{"version":"Version 0.1.0-SNAPSHOT","lastcommit":"75473700d5befa953c45f630c6d9105413c16fe1"

setting the customfields programmatically is working fine.

hi, think I’m running into the same issue

I have the following in logback.xml

    <appender name="console" class="ch.qos.logback.core.ConsoleAppender">
        <encoder class="net.logstash.logback.encoder.LogstashEncoder">
            <customFields>
                {"serviceContext":{"service":"foo"}}
            </customFields>
        </encoder>
    </appender>

When using logstash-logback-encoder 7.0.1, I’m getting the follow error

02:17:46,889 |-INFO in ch.qos.logback.core.joran.action.NestedComplexPropertyIA - Assuming default type [net.logstash.logback.fieldnames.LogstashFieldNames] for [fieldNames] property

If I change customFields to {"serviceContext": "foo"}, things work as expected.

I tried upgrading logback-classic to 1.3.0-alpha10, but no log was generated
