7/17/2018 9:12am - David Mack - dave@secondavenuelearning.com - I have the latest Canvas running on Ubuntu server 18.04. This is running on a virtual on my Windows Pro 10 laptop. I am trying to get an LTI test app that works perfect with Moodle to work with Canvas. I have been successful in getting a launch to work great. The problem is that I don't get the two parameters from Canvas so I can return a grade. What is the magic to make this happen. I have copy pasted XML configuration and this XML allows the launch to be successful. Obviously I am missing something and the only thing that I can think of is there's something in the XML config that I am missing. I read that you must be a student in order for these two variables to be passed to the LTI provider. I assume that "student" and "learner" are one and the same. When the launch is done the info says this is a "learner". Is there any help that you can offer me? Thank you. David Mack.
