I've received some more information via email. Shane's colleague did a quick lookup on IMS global LTI tool compare: https://www.imsglobal.org/toolcompare.html
It looks like the parameter in question (lis_course_offering_sourcedid) is not defined in Mahara LTI Optional Params list. I had a dig through the code because I knew that we had written code that would ignore certain parameters that Mahara doesn't know / need to know that Canvas was sending through. It turns out that it was parameters prefixed with "custom", which is not the case here. Thus, an exception is thrown as expected because it does need to be dealt with. It would be worthwhile checking again if we can / should cast the net wider so as not only to ignore "custom" but others as well that could come through and let admins know when the site is not in production mode as was done at https://git.mahara.org/mahara/mahara/commit/e120d8fd2a6c20b8ae510d1e16deb113dbd6f85d so they can decide whether further action needs to be taken or if the parameter can be ignored without any issue. ** Changed in: mahara Status: New => Confirmed ** Changed in: mahara Importance: Undecided => Medium -- You received this bug notification because you are a member of Mahara Contributors, which is subscribed to Mahara.

I have attached a screen shot on an email as it keeps all the elements of the email together which has screenshots and text which is not a combination supported by this bug submission text editor.
