Language data not being recognized on custom Language

v6
9

Got it–I was able to get this working with the following code:

const topNode = NodeType.define({
  id: 0,
  name: "topNode",
  top: true,
  props: [
    [
      languageDataProp,
      defineLanguageFacet({
        commentTokens: { block: { open: "/*", close: "*/" }, line: "//" },
      }),
    ],
  ],
});

Thank you for your help!
