Trailing slash removed from REST API
As of Spring Framework 6.0, the trailing slash matching configuration option has been deprecated and its default value set to false.
This means that previously, a controller w/ @GetMapping("/jobs/executions")
would match both "GET /jobs/executions" and "GET /jobs/executions/".
As of now, "GET /jobs/executions/" will result in 404.
Solution
If you are calling the Dataflow REST API directly, remove any trailing slashes from the endpoint urls.
