Delayed loading not work

The component always show “No Sub-options” when using loadOptions, here is the code:

 async loadOptions({action, parentNode, callback}) {
        if (action === LOAD_CHILDREN_OPTIONS) {
          const {name} = parentNode;
          if (name) {
            const {data} = await getSubCategory({name});
            parentNode.children = data;
            callback();
          } else {
            parentNode.children = [];
          }
        }
      }

How can I solve this problem?
