Axios not returning data while using asynch await

This is my axios function

const requestAllSubPosts = (sub,epoch,count) => {

  const res = {};
  const sub_url = `https://api.pushshift.io/reddit/search/submission/?subreddit=${sub}&limit=1000&sort=desc&before=${epoch}`;     


 return axios
      .get(sub_url)
      .then(response => {
        const d = response.data.data;

        if(d.length > 0) {
          subFetchEpoch = d[d.length - 1].created_utc;

          subDataArray = subDataArray.concat(d);        
          count++;

          requestAllSubPosts(sub,subFetchEpoch,count)

        }
        else {
           console.log('data-empty');

           res.data = subDataArray;
           res.epoch = subFetchEpoch;

           console.log(res); <-- WORKING
           return  res ; <-- NOT WORKING


        }


      })
      .catch(error => {
        return  error.message 
      });


}

I'm using axios in a sort of loop, and fetching data till the response is empty. After that I want to return the appeneded data in the parent function.

This is the parent function. I call on axios and logging the response. But I'm not getting any response

async function  fetchAllSubPosts (sub, epoch)  {

      const today = moment(new Date()).valueOf();
      // let ep_a = moment(ep).valueOf()

      let dataArray = [];
      let resp = await requestAllSubPosts(sub, ep, 1) 
      console.log({resp}); <-- NOT WORKING

}

When you recursively call requestAllSubPosts() the then() has no return and so by default will return undefined to the next then() or await in the chain

You want to return the promise from the recursive call.

Change:

 requestAllSubPosts(sub,subFetchEpoch,count)

To

return  requestAllSubPosts(sub,subFetchEpoch,count)
