const pd = new PipedreamClient({
  projectId: process.env.PIPEDREAM_PROJECT_ID!,
  clientId: process.env.PIPEDREAM_CLIENT_ID!,
  clientSecret: process.env.PIPEDREAM_CLIENT_SECRET!,
  projectEnvironment: "production",
})

const result = await pd.actions.run({
  id: "arcgis_online-list-layer-fields",
  externalUserId: "{external_user_id}", // any stable ID for this user in your system
  configuredProps: {
    arcgis_online: { authProvisionId: "apn_xxxxxxx" },

    layerId: "Layer",
  },
