我发现了我的错误。需要返回

const id = action.payload.container_id;
  console.log("id", id);
  console.log("action payload", action.payload);
  // state.containers
    let key = 0
    state.containers = state.containers.map((cont) => {
      console.log("key", key);
      if (cont.info.id === id) {
        console.log("found container atrr", state.containers[key].info.title);
        
        state.containers[key].info.attributes.push({
          id: action.payload.container_attr_id,
          value: action.payload.value,
          name: action.payload.name,
        });
      }
      key = key + 1
      **return cont**
    });
