Question: GraphQL calls are failing after upgrade to Spring boot 4 which include spring graphql 2.0.1

[flinden68]

We are using spring graphql for our graphql calls.
Everything works fine till I upgraded to spring boot 4.0.1.

in my gradle file I didn't change anything, but the latest spring graphql is pulled in.

For my test I switched from from testImplementation("org.springframework.graphql:spring-graphql-test") to testImplementation("org.springframework.boot:spring-boot-starter-graphql-test") as recommended in the spring boot 4.0 migration guide. https://github.com/spring-projects/spring-boot/wiki/Spring-Boot-4.0-Migration-Guide

My test looks like this.

        server.dispatcher = dispatcher
    }
}

When I debug the test. I will reach the breakpoints in my code, just before the return of the method with the querymapping.

But then I get an error in the console

What could be the cause? What do I miss?

It looks like your application is using an outdated version of graphql-java. Please check your dependency management or share a minimal sample application.

Thanks, Will check when I am back at my laptop.

@bclozel I found the issue. It was as you already mentioned a dependency issue. Somewhere in de code there was a graphql-java bom loaded with version 24.0.
When I removed this dependency everythings run fine again

Thanks for letting us know
