Error creating repo

[chidaran-aetna]

Error while creating repo due to visibility options.

Error message I receive is :
"message":"Invalid visibility. Valid visibilities are: public, private, internal"

source I'm using is :

    GHRepository ghRepository = github.getOrganization(request.getOrg())
            .createRepository(request.getName())
            .description(request.getDesc())
            .defaultBranch("main")
            .team(ghTeam) //retrieve the team from the Request
            .visibility(Visibility.INTERNAL)
            .create();
