I thought I might be able to stuff a react app into a netsuite portlet… but I am getting this error:

{
  "type": "error.SuiteScriptError",
  "name": "INVALID_API_VERSION_FOR_FORM",
  "message": "You cannot use this API with this version of SuiteScript.",
  "stack": [
    "createError(N/error)",
    "render(/SuiteScripts/repo/portlets/react.js:9)"
  ],
  "cause": {
    "type": "internal error",
    "code": "INVALID_API_VERSION_FOR_FORM",
    "details": "You cannot use this API with this version of SuiteScript.",
    "userEvent": null,
    "stackTrace": [

    ],
