    for (const name of all_view_model_names) {
      const model = Models(name)
      const instance = new model({}, {silent: true, defer_initialization: true})
      const attrs = instance.attributes_as_json(true, deep_value_to_json)
      strip_ids(attrs)

      const python_defaults = get_defaults(name)
      const bokehjs_defaults = attrs
      if (!check_matching_defaults(name, python_defaults, bokehjs_defaults)) {
        console.log(name)
