Error/bug with deep linking 1.3 in Brightspace

Question

I'm trying to test our LTI 1.3 integration. It works in other LMS systems, but not Brightspace, so it leads me to believe that there's either a bug in Brightspace, or that there's a setting I'm missing.

When I get through the deep linking process, I get a generic message. Upon checking logs, it shows "Something went wrong while processing deep linking content item" but no further detail.  Error ID is 49639615654268072787527300474811764829288079927485136898.0 on the devcop instance.

Where can I go from here to dig in deeper to the problem?

Do you mean the custom parameters of Deep linking response ??

I am not sure whether the response needs this claim. In the LTI 1.3 spec, the example does not.

Or does this claim become mandatory in Brightspace ?

Hello! Related to the above, I'm looking for the documentation on LTI Deep Linking, but the link above (https://community.d2l.com/brightspace/kb/articles/5428-lti-advantage-developer-faq#deep-linking) no longer seems to work. Does anyone know where the docs are now?

I wonder too… perhaps I'm not creating this in the correct spot within Brightspace? Here's what I've done so far:

* Manage Extensibility, then registerd a new LTI Advantage tool
* Create a new deployment for the tool
* Create a new link

My goal is to create an assignment the student can do that would end up being graded and posted back to the gradebook.

Right now, the only place I can seem to find my tool/deployment/link is by clicking on "Content" then "Add Existing" then finding it listed under "more."
