Undefined property: stdClass::$annotation in plugins/googleplus/model/class.GooglePlusCrawler.php

[petdance]

I now constantly get warnings from my cron job saying:

PHP Warning:  json_encode(): Invalid UTF-8 sequence in argument in /srv/thinkup/_lib/class.DashboardModuleCacher.php on line 225
PHP Notice:  Undefined property: stdClass::$annotation in /srv/thinkup/plugins/googleplus/model/class.GooglePlusCrawler.php on line 210
PHP Notice:  Undefined property: stdClass::$annotation in /srv/thinkup/plugins/googleplus/model/class.GooglePlusCrawler.php on line 210

The line of code in DashboardModuleCacher.php is the return from getHotPostVisualizationData()

        return json_encode(array('rows' => $result_set, 'cols' => $metadata));

The lines of code in GooglePlusCrawler.php are in fetchInstanceUserPosts() and look like:

                } elseif ($item->verb == "share") {
                    $post['post_text'] = $item->annotation;
                    $should_capture_post = true;
                }

Are the warnings related? I don't know.

Would love to see the data coming out of the db that's causing the Invalid UTF-8 sequence error. Any way you could do a print_r on $result_set and $metadata?

[petdance]

Anything magic I need to do besides just kicking off a run from the command line rather than my normal cron job?

[ginatrapani]

Nope, should be able to just do a run from the command line (and capture the output). Thanks for troubleshooting this Andy.

I'm getting the same problem, here is the output from my configuration:

$result_set: 2012-11-09 07:53:25 | 4.4MB | SUCCESS| DilbertDave | TwitterPlugin::crawl,106 | Starting to collect data for DilbertDave on Twitter. $metadata: 2012-11-09 07:53:25 | 4.8MB | INFO | DilbertDave | TwitterAPIAccessorOAuth::__construct,111 | Errors to tolerate: 5

Hope this is useful

PHP Warning:  json_encode(): Invalid UTF-8 sequence in argument in /srv/thinkup/_lib/class.DashboardModuleCacher.php on line 227

[OnTheFenceDevelopment]

Lol - looks nothing like what was sent to my log file, if you can post what you did to create that output (like I said above, I'm not a PHP dev) then I can try to provide some additional data.

[petdance]

@OnTheFenceDevelopement The dump is per Gina's request a few entries back. It's not in my log file.

[OnTheFenceDevelopment]

Hmm ... I've added print_r($result_set) & print_r($metadata) statements just before the 'offending' line and run the thinkup script via the command line while redirecting the output to a file - that's what I get.

Oddly, my system has stopped complaining now and it ran to conclusion just now.

[petdance]

I have stopped receiving the Invalid UTF-8 sequence errors in my cron runs, but the Undefined property: stdClass::$annotation is still alive and kicking. I have updated no software.

[ginatrapani]

The Undefined property error happens when you share a Google+ post without making a comment about it. (Your comment is "annotation", and the property doesn't exist if there is none.) I'm working on a fix now with tests. Thank you!
