Unknown node type

[Nefcanto]

Hello,

This is my Menu.jsx content:

import FingerprintIcon from '@mui/icons-material/Fingerprint'

const ModulesMenu = [
    {
        title: "Entity Types",
        icon: FingerprintIcon,
        path: "/entityTypes",
        superAdmin: true
    }
]

export default ModulesMenu

And this is the AST generated for this, using nightly-esprima:

                                        "kind": "init",
                                        "method": false,
                                        "shorthand": false
                                    }
                                ]
                            }
                        ]
                    }
                }
            ],
            "kind": "const"
        },
        {
            "type": "ExportDefaultDeclaration",
            "declaration": {
                "type": "Identifier",
                "name": "ModulesMenu"
            }
        }
    ],
    "sourceType": "module"
}

When I try this code on this AST, I get unknown node type error:

    estraverse.traverse(ast, {
        enter: function (node, parent) {
            console.log(node.type)
        },
    });

This is the full error stack:

undefined

What is wrong here?

If you want to traverse JSX nodes or any other nodes that are not JS nodes, you must use the custom visitor keys feature. See the README for documentation.
