On the edit page, after the component gets mounted ( componentDidMount() ), the app dispatches an action to retrieve a specific post details: dispatch({ type: FETCH_POST, id: 'post-id' }) I am using redux-saga and want the above call to return a Promise so that I can access the API response. Right now, without a callback/Promise, I ended up with defining a

问题 I have a react saga code here which does not run in sequence: yield put({ type: 'SHOW_LOADER', loading: 'workflowobject' }) #yield to initiate the loader const states = yield call(() => axiosInstance.get(`/workflow-object/state/list/${action.workflow_id}/${action.workflow_object_id}/`)) const newState = states.data.map(item => ({ // some operation to shape my data , might this be the issue? iteration: item.iteration, ...item.state })); yield put({ type: "STORE_WORKFLOW_DATA", payload:
