      <description>by Antonia Bonaccorso. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;Hi Fernando,&lt;br&gt;
&lt;br&gt;
This note informs that the parameter $extracodeexpertparams required in this old version of the plugin is deprecated and might cause problems. As this version of the plugin was meant for Moodle versions that no longer receive general nor security support, we recommend to update to the newest version of the plugin. By doing so you will also get rid of the note.&lt;br&gt;
&lt;br&gt;
Best regards,&lt;br&gt;
Antonia&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

      <description>by Fernando Oliveira. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;Thanks for this plugin. Any chance of getting this fixed in version 2022082300: &lt;br&gt;
&lt;br&gt;
Deprecated: Required parameter $extracodeexpertparams follows optional parameter $typeid in /home/www/public/question/type/lti/locallib.php on line 360 &lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

does this plugin work with LTI 1.3? As far as I see, it is limited to LTI 1.0/1.1&lt;br&gt;

      <description>by Susana Caixinha. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;Hello we're having problems with the plugin in Moodle 4.0.3+ (Build: 20220826). when we try to insert a new question it runs into an error: Exception - Call to a member function instance_form_definition_after_data() on null&lt;br&gt;
&lt;br&gt;
Have you tried the plugin in the new version of Moodle?&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

      <description>by José Carvalho. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;Hi, I just reported an issue named &quot;Error running plugin qtype_lti on Moodle v3.11.2+ (Build: 20210812)&quot; on GitHub.&lt;br&gt;
Has anyone seen a similar behaviour?&lt;br&gt;
&lt;br&gt;
NOTE: On Github, the latest release (May 25) is identifyed as 0.3. However, file version.php states it is version 04 ($plugin-&amp;gt;release = '0.4 for Moodle 3.5+';)&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

      <description>by João Rodrigues. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;I reported a bug named &quot;Selecting a preconfigured tool does not save the secure tool URL&quot; (in the Bug Tracker).&lt;br&gt;
Could anyone try to reproduce and/or comment?&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

      <description>by Татьяна Берленко. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;Thanks for the answer!&lt;br&gt;
LTI provider (LTI v1.1) uses to send a score to a moodle POST request to lis_outcome_service_url with parameters from the LTI-launch request (lis_outcome_service_url, lis_result_sourcedid, oauth_consumer_key), and sent score is displayed in gradebook (for standart External tool). &lt;br&gt;
 &lt;br&gt;
However, when working with the plugin, we catch this error (to data in database). Where should the required scores be located so that the plugin handles everything correctly when I click &quot;Check&quot;? (Since the plugin does not make requests to LTI provider)&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>

      <description>by ETH Zürich. &amp;nbsp;&lt;p&gt;&lt;div class=&quot;no-overflow&quot;&gt;&lt;div class=&quot;text_to_html&quot;&gt;It seems your LTI provider returns an invalid grade (NAN in your case). The result needs to be from 0 up until 1. (Fractions allowed)&lt;/div&gt;&lt;/div&gt;&lt;/p&gt;</description>
