"Devel" button on "devel/routes" doesn't show target route info for JSON:API Routes
Issue #3102246 on drupal.org by GuyPaddock.
If I navigate to /devel/routes
and click the "Devel" button next to any JSON-API routes (e.g. jsonapi.image_style--image_style.collection
), the route information that appears is for the devel module rather than the target route.
In addition, a message like the following appears if I navigate to a subsequent page:
Unable to load route for url '/jsonapi/image_style/image_style'
It would seem that Devel's routes info page is not compatible with JSON:API's routes, or perhaps it is not capable of displaying dynamically-generated routes like JSON:API uses.
