Trending @Capgemini; Help regarding IKEA project

Currently, I am on the bench(fresher), and my primary skill is Java full stack with React. Recently, I was told I was selected for the IKEA project, but the role is webmethods, not Java, which I thought it would be. Now, I am in a dilemma whether to accept this or not. I want to know the future scope of webmethods? Or else, should I reject this and try applying for Java projects?
