IllegalStateException: At least one top-level operation source must be registered

[lekhalingeshwar]

With spring boot 3.2.4 and graphql-spqr-spring-boot-starter 1.0.1, I get the following exception when trying to run the project,

Caused by: java.lang.IllegalStateException: At least one top-level operation source must be registered

When I use graphql-spqr-spring-boot-starter 0.0.4, my application runs without any error but the graphql url http://localhost:8080/gui is not exposed properly.

{"type":"about:blank","title":"Not Found","status":404,"detail":"No static resource graphql.","instance":"/gui"}

So, when I tried to upgrade to latest spqr jar, I'm getting the previous error.

Note:

• There are no duplicate versions of spqr jars in the classpath
• My application was working fine with springboot 2.5.14 and spqr 0.0.4.
