Hi All

I am having difficulties connecting to Canvas from Moodle using Advantage LTI.

I'm getting this error message.

I'm not familiar with Canvas so does anyone have any Canvas tips.

Thanks

Gareth

This post (and its parent) from a few months back has a setup procedure that is known to work.

Where are you getting this error, or can you enable debugging on this environment to see the output of exactly what's calling it? It's almost surely being thrown by a call to create a URL string on a MoodleURL object, but being called on a variable with a string type.

Also, did you use the documentation on Charles' github at the end of that thread? That's for a very specific use-case where you want everyone using the LTI tool to see one specific quiz, course, or other "Published as LTI" resource. Typically, you would want to set it up so that users can use deep-linking to select the resources they want to publish, since that's the killer feature for LTI versions higher than 1.1
