Hello! We have successfully used your plugin in the past to integrate a survey via LTI with the Open eClass LMS. I can see from backups that the LimeSurvey instance we used was version 4.6.2+210512, with LTIPlugin version 1.0.5, but unfortunately that server isn't currently online.

We have just setup a new LimeSurvey instance, version 5.6.9+230306 with LTIPlugin 1.1.0, and while initially everything went fine, when activating the survey via LTI the following error appears:

500: Internal Server Error
Illegal offset type in isset or empty
An internal error occurred while the Web server was processing your request.

The new server is running Apache with mod_php (we tried PHP 8.0, 8.1 and 8.2 with the same result).

It seems the exception is caught and full details don't appear in the logs (is there a way to enable full error logging in LimeSurvey?) but by adding a line to print $exception->getTraceAsString() in vendor/yiisoft/yii/framework/base/CErrorHandler.php I captured the following backtrace, in case it helps:

#0 [internal function]: LTIPlugin->newDirectRequest()

#12 /var/www/html/limesurvey/index.php(192): CApplication->run()
#13 {main}

I also tested it through an LTI activity in Moodle and got the same error.

We'll continue trying to debug the problem, but I'd be grateful for any ideas or a possible solution - thanks in advance!

Hi!
I got this error when trying to upload the plugin with the upload facility:

500: Internal Server Error
Argument 1 passed to ExtensionConfig::__construct() must be an instance of SimpleXMLElement, bool given, called in /opt/bitnami/apache/htdocs/application/models/ExtensionConfig.php on line 162

I tried uploading to the plugins directory manually but it didn't recognize the plugin either.

I'm using Release 5.3.14 of LimeSurvey

Thanx for programming this plugin. I use it with Moodle and a Limesurvey Docker-Image.

After switching to HTTPS i changed $_SERVER['HTTP_HOST'] to the real URL (not localhost)

I can take the survey und it gets saved. - But no Informationen gets saved to der 4 additional attributes. I can only get access to the survey more than ones.

Hi,
We have LimeSurvey 5.3.29+220801 with the latest LTI Plugin, connecting to an Open edX Ironwood instance. We use the standard LTI consumer, graded component.
In many random cases, students complete the form but the component fails to grade. In other cases it works well.

Is there any configuration tip? Other people reporting the same issue?
