You need to have async keyword for the inner function

export function getData() {
  return async (dispatch) => {
    try {
      const data = await API.graphql(graphqlOperation(query))
      dispatch({ type: "DATA_AVAILABLE", data: data.data.listData.items });
    } catch(err) {
      console.log('error: ', err)
    }
  }
}

Getting a error message saying Parsing error: Can not use keyword 'await' outside an async function from below code for Redux action.

What is the proper way to write this?
```
export async function getData() {
  return (dispatch) => {
    try {
      const data = await API.graphql(graphqlOperation(query))
      dispatch({ type: "DATA_AVAILABLE", data: data.data.listData.items });
    } catch(err) {
      console.log('error: ', err)
    }
  }
}
```

  return (dispatch) => { is not async

  return async (dispatch) => { no need of async in export async function getData()

  @CertainPerformance also tried export const getUserJournals = () => async (dispatch) => { ... } but didn't work :(

It actually seems to be working when it on my dev environment with AWS amplify but does not working on my local. Not sure why lol

It may so be the case that qraphql query isn't working correctly in your local
