We are continuing to work on a fix for this issue.

We've identified an issue that's similar to yesterday's issue with Canvas. An error message would show a "An Error occurred while validating the launch of Kami" message while teachers try to view Kami documents in Speedgrader and create assignments using the External Kami Tool.
We know this is caused by a recent update where Canvas' LTI integration stops not sending us information about the course, and this is why it's predominantly affecting teachers only.
We've developed a fix but are having issues with one of our engineering tooling providers to roll out the fix.
