Axios/Express routes work on local but not heroku

I have an app that works fine on local but once deployed to heroku, I keep getting these errors

xhr.js:175 POST https://boiling-fjord-32011.herokuapp.com/edit 404 (Not Found)

xhr.js:175 GET https://boiling-fjord-32011.herokuapp.com/aboutme?id=auth0%7C58f51bca84f7f1600bac4b5d 404 (Not Found)

createError.js:15 Uncaught (in promise) Error: Request failed with status code 404
    at createError (createError.js:15)
    at settle (settle.js:18)
    at XMLHttpRequest.handleLoad (xhr.js:77)

I am wondering why the heroku url is being attached to my POST and GET axios requests 'aboutMe' and '/edit'

Code for post/get requests in my components

getResults(){
          console.log("getResults from db")
          console.log(this.state.user_id)
          return axios.get('/aboutme', {
            params: {
              id: this.state.user_id
            }
          }).then(function(response){   
          console.log("RESPONSE IN ABOUT ME", response)   
            return response;
          });
        }

     componentDidMount(){


            this.getResults().then(function(response){
                console.log("pushing to the state in componentDidMount");
                console.log("THE RESPONSE", response);
                if (response.data[0]!=null){
                this.setState({
                  goal: response.data[0].goal,
                  weight: response.data[0].weight,
                  diet: response.data[0].diet,
                  location: response.data[0].location,
                  inspiration:response.data[0].inspiration
                })           
                }


        }.bind(this))
      }

 dataChanged(data) {
          this.props.changedData();    
          console.log("dataChanged!!")
        this.setState(data, function(){
          console.log("STATE IN SETSTATE CALL BACK", this.state)
        axios.post("/edit", this.state)
        .then((data) => {
           console.log("Edits then", data);  
        })
        .catch((err)=>{
           console.log("Edits catch", err);   
        })
        })
      }
