org.dataloader.DataLoaderRegistry error while initialization

[KushagraBindal]

I am using below set of jar in my application.
compile files('libs/latest/graphql-java-servlet-6.1.3.jar')
compile files('libs/latest/graphql-java-16.2.jar')
compile files('libs/latest/graphql-java-tools-5.2.4.jar')
compile files('libs/latest/graphql-spring-boot-autoconfigure-5.0.2.jar')
compile files('libs/latest/graphql-spring-boot-starter-5.0.2.jar')
compile files('libs/latest/antlr4-runtime-4.9.2.jar')
compile files('libs/lombok-1.16.18.jar')
compile files('libs/latest/graphql-java-extended-scalars-16.0.1.jar')

While initializing the beans I am getting below error.

Can someone please help in resolving this issue.

You're using outdated versions of this library. It's also unclear from your report which ones you're explicitly defining yourself and which ones are transitive. From the GraphQL ones you should only be including the graphql-spring-boot-starter dependency version 11.1.0. All the other ones (tools, servlet, GraphQL-Java) are pulled in by that starter (= transitive), which ensures compatibility.

thanks @oliemansm for your quick response.

I was able to resolve this issue by adding java-dataloader-2.2.3.jar in WEB-INF/lib folder as of now and application is now up & running.

Thanks for your time, I am doing POC as of now to integrate my existing web application with GraphQL. But I will take your provided input as a feedback for me and will do it in the same at the time of complete implementation.

thanks @oliemansm I put the POM entry and all dependencies loaded properly.
