Subject Re: NiFi 1.2.0 REST API problem
Date Thu, 08 Jun 2017 21:12:16 GMT
I have not been able to find anything in the logs that is useful, but I'm
not sure I enabled all of the logging that I need to.

But I did find some more information, if I restart the NiFi service the
InvokeHTTP call starts working and we have two other flow patterns that
have the same issue.  In each case it is always the second InvokeHTTP
processor that fails.

This is how I have the logging set currently:
    <logger name="org.apache.nifi" level="INFO"/>
    <logger name="org.apache.nifi.processors" level="DEBUG"/>
    <logger name="org.apache.nifi.processors.standard.LogAttribute"
level="WARN" />

    <logger name="org.apache.nifi.web.api.config" level="DEBUG"
        <appender-ref ref="USER_FILE"/>

All of the other logging is set to its default value.
