LTI custom Issue

Question asked by Wilson Espinosa on Nov 8, 2017

I am trying to use the variables that LTI has to obtain information on the sections of a course (http://www.imsglobal.org/specs/ltiv1p1/implementation-guide#toc-19), but when using them in the lti element: custom of the MXL structure that the application invokes, the values are not being loaded.

The only variable that loads information is $Course.Section.sourceId but it brings the data of the course.

 

How should I use the variables?.

Should an additional configuration be done?
