404 Error message for Report image GET request via JSON:API

[patrickkaleta]

I'm trying to add the "include in report button" functionality, but after updating my local csis instance to the newest version of the csis, I'm receiving an error when trying to make a GET-request for a Report image:
The "entity" parameter was not converted for the path "/jsonapi/node/report_image/{entity}" (route name: "jsonapi.node--report_image.individual")
The GET-request was working prior to that update.

@fgeyer16: have there been any other changes made to the (JSON:API) Rest configuration, which I need to manually add to my local instance?

Error was caused by a missing file, so UUID didn't exist anymore, which lead to this meaningful error message.
