REST API stopped working ("errorCode": "EX0")

A few days ago (maybe after the upgrade to my REST API functions stopped working.

For example when trying to create a new topic (POST to /forums/topics) I'm getting this response:


"errorCode": "EX0",
"errorMessage": "UNKNOWN_ERROR"

And my system log show OutOfRangeException::0 error:


#0 /home/hwzone/public_html/community/system/Content/Api/ItemController.php(282): IPS\Patterns\_ActiveRecord::load(0)
#1 /home/hwzone/public_html/community/applications/forums/api/topics.php(127): IPS\Content\Api\_ItemController->_createOrUpdate(Object(IPS\forums\Topic))
#2 /home/hwzone/public_html/community/system/Content/Api/ItemController.php(315): IPS\forums\api\_topics->_createOrUpdate(Object(IPS\forums\Topic))
#3 /home/hwzone/public_html/community/applications/forums/api/topics.php(193): IPS\Content\Api\_ItemController->_create(Object(IPS\forums\Forum), Object(IPS\Member))
#4 [internal function]: IPS\forums\api\_topics->POSTindex()
#5 /home/hwzone/public_html/community/system/Api/Controller.php(73): call_user_func_array(Array, Array)
#6 /home/hwzone/public_html/community/system/Dispatcher/Api.php(224): IPS\Api\_Controller->execute(Array, true)
#7 /home/hwzone/public_html/community/api/index.php(13): IPS\Dispatcher\_Api->run()
#8 {main}

I'm using this generic code to send the API test request:

$fields = array(
		'forum' => 16,
		'author' => 84343,
		'author_name' => 'test',
		'title' => 'test',
		'post' => 'test',
		'hidden' => 0,
		'tags' => 'test',
	$curl = curl_init( $communityUrl . '/api/forums/topics' );
	curl_setopt($curl,CURLOPT_USERPWD, "{$apiKey}:");
	curl_setopt($curl,CURLOPT_POSTFIELDS, $fields);

	$response = curl_exec( $curl );


This was working perfectly fine until a few days ago, what could have cause this? and how should I fix this?

quick update: the ItemController.php file was indeed last changed on 7 December, when it stopped working.

Also please note that the REST API request actually does indeed create the topic - but it does not include the actual post content in it - and trying to enter the topic results in an error message ( 2F173/L ). In the database, no posts are created under that topic id.

another quick update:  POSTing to forums/posts (adding a new post to existing topics) works fine, so the issue is only with creating new topics...
