Server crashing when update version from 0.17.14 to 0.17.15

[PratikBurkhawala]

I am new to Ktor and KGraphQL so not able to currently figure out why server crash when I update kgraphqlVersion present in file: gradle.properties to 0.17.15 from 0.17.14. When on v0.17.14, it works fine but not with v0.17.15

Please check the attached txt file for crash and zip file for project. It is simple Hello World project.

To reproduce the crash, please open project in an IDE and run the Application Class, then using either Playground or Postman with URL: (POST) http://0.0.0.0:8080/graphql and Body (GraphQL) query { hello } and version of kgraphqlVersion=0.17.15 in file gradle.properties , the crash will reproduce.
