The Canvas error "Couldn't find valid settings for this tool" may be caused by a URL mismatch between the tool configuration and your Canvas environment.

This mismatch can be caused when your Canvas environment has more than one way to access it such as the Canvas URL and a vanity URL. Currently, the Canvas tool configuration can only support a single URL which needs to be the Canvas URL. Vanity URLs used by your school will not work correctly. If you need to change the URL in the configuration, your Sage Technical Implementation Specialist can make this switch for you.
