When I use 1.3.0-M2 or 1.3.0-M3 I get the stacktrace below. The attached testcase is based on Spring Boot and Spring WebFlux. You start the server with ./gradlew bootRun, and in a 2nd terminal you invoke the URL http://localhost:8080/api/00000000-0000-0000-0000-000000000001 with an HTTP GET request and the header value Accept: application/hal+json.

You can enforce Spring HATEOAS 1.3.0-M1 in build.gradle.kts by uncommenting from line 39 till line 43. When you restart the server and again invoke the same URL, then the issue is gone.

Here is the testcase

The stacktrace:
