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();
