https://www.drupal.org/node/2666230#10 → : In case you still have this problem (or for future readers): Drupal Console adds a canonical link path to your generated entity type config entity, even though the route for the canonical path doesn't exist. You need to remove the canonical link from the "links" collection in the @ConfigEntityType annotation.
#2629864: Error in 'workflow_config_transition' when deleting a Workflow and pathauto enabled. → : Berdir: "You don't need to have edit-form for deleting, that was an unfortunate conflict with pathauto. We'll make sure to avoid that in pathauto. However, you might have further conflicts in the future with other modules.
If you don't have an edit form, then you don't need such a link template. So you don't have to add that unless you actually have that form, which doesn't seem to be the case right now. The real problem then seems to be that you have a canonical link template but aren't actually using it. The route is commented out. Other modules *will* assume that when you have a canonical link template, that there is a place to view the entity (that's what's done in 99% of the cases on canonical routes/link templates).
Config entities are in most cases not viewed, so they shouldn't have a canonical link template.
