Hi, what errors you are encountering?

After I click the "check" button, I get the following error: https://drive.google.com/file/d/1_sjdkxowsz79-iiR57gfzqlvfSGxMbPf/view?usp=sharing
If required, I can also send the task settings.

Text of message:

Thank you!

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)

Thanks for the answer!
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).

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 "Check"? (Since the plugin does not make requests to LTI provider)

I reported a bug named "Selecting a preconfigured tool does not save the secure tool URL" (in the Bug Tracker).
Could anyone try to reproduce and/or comment?

Has this been tested in Moodle 3.11?

Hi João, its tested on 3.11 and we also have added more features. You can download the latest from github, or you can wait until October once we package the final version for the community here.

Hi, I just reported an issue named "Error running plugin qtype_lti on Moodle v3.11.2+ (Build: 20210812)" on GitHub.
Has anyone seen a similar behaviour?

NOTE: On Github, the latest release (May 25) is identifyed as 0.3. However, file version.php states it is version 04 ($plugin->release = '0.4 for Moodle 3.5+';)

For future reference, we were able to solve the issue we were having by installing plugin release = '0.4 for Moodle 3.5+' / version = 2021080302 (as instructed by the development team)

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

Have you tried the plugin in the new version of Moodle?

Hi, could you please report the issue here: https://github.com/ethz-let/moodle-qtype_lti/issues

Hi, the latest version is working and solved the problem

thanks

Hi there,
does this plugin work with LTI 1.3? As far as I see, it is limited to LTI 1.0/1.1

Thanks for this plugin. Any chance of getting this fixed in version 2022082300:

Deprecated: Required parameter $extracodeexpertparams follows optional parameter $typeid in /home/www/public/question/type/lti/locallib.php on line 360

Hi Fernando,

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.

Best regards,
Antonia
