[jira] [Commented] (CAMEL-9557) Facebook consumer throws IllegalArgumentException with reading parameters

["Justin W (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/CAMEL-9557?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=15127751#comment-15127751 ] 

Justin W commented on CAMEL-9557:
---------------------------------

The commit for CAMEL-9472 adds the following line in FacebookPropertiesHelper.configureReadingProperties which causes the error I believe:

{code}
configuration.setReadingOptions(readingProperties);
{code}

[GitHub|https://github.com/apache/camel/commit/846b097c2b881eac68328800bdd6a9d3017921c7]

I've reverted to 2.16.1 until this is fixed.

>                 URL: https://issues.apache.org/jira/browse/CAMEL-9557
>             Project: Camel
>          Issue Type: Bug
>          Components: camel-facebook
>    Affects Versions: 2.16.2
>         Environment: OpenJDK Runtime Environment (IcedTea 2.6.4) (Arch Linux build 7.u95_2.6.4-1-x86_64)
>            Reporter: Justin W
>
> I've configured a polling Facebook consumer with nearly default Spring configuration as follows:
> {code}
> <camel:from uri="facebook://getFeed?
>     reading.since=2016-01-01T00:00:00Z&amp;
>     userId=myUserId&amp;
>     consumer.delay=60000&amp;
>     oAuthAppId=[s]&amp;
>     oAuthAppSecret=[s]&amp;
>     oAuthAccessToken=[s]
>     "/>
> {code}
> However, an IllegalArgument is thrown with any reading.* parameter regardless of endpoint:
> {code}
> java.lang.IllegalArgumentException: No matching operation for getFeed, with arguments [readingOptions, reading, userId]
> {code}
> On debugging, the method FacebookEndpoint.configureProperties sets two properties on the configuration object: (readingOptions, reading).
> {code}
> FacebookPropertiesHelper.configureReadingProperties(configuration, options);
> {code}
> readingOptions is a Map which is finally size 0 after all the relevant properties are extracted into the reading parameter. However, it isn't nullified.
> In the subsequent method initState(), it tries to look for a method in FacebookMethodTypes with the signature:
> {code}
> getFeed(String userId, Reading reading)
> {code}
> Because readingOptions is non null, it looks for a readingOptions parameter as well which doesn't exist, throwing the Exception.
> Is there a workaround I can use for the moment? Thanks!
