How to break out of chain after a condition? I can't use try and catch because of the way I take the response(very bad response)

const fetchData = async dispatch => {
      await axios
        .get("/url.php?"})
        .then(response => {
          if (response.data.success === false) {  
            setFetchingOk(false);
            logoutUser();

            //Here i want that the chain(everything below) to stop totally

          } else {
             // bla bla bla               
            return response.headerFields
          }
        })
        .then(headerFields => 
             //bla bla bla      
            )
        )
        .then(response => {
        });
    };

Edit: I solved it by throwing an error at my condition block like

throw new Error("Not authorized");

and then at the end of the chain adding

  .catch(function(error) {
    console.log(error);
  });

Now it doesn't give Fatal Error

you can `throw` an error inside a `.then` – Jaromanda X Sep 10 '19 at 12:25
I deleted a lot of code to make it simple to read, probably I have messed up the brackets – Besart Marku Sep 10 '19 at 12:26
sure, but that makes the code unreadable and hard to figure out what you want to do ... but, throwing an error or returning a Promise.reject() seem to be what you want to do – Jaromanda X Sep 10 '19 at 12:27
where do exactly I return a Promise.reject() ? at the line where I say i need to stop the rest of code? – Besart Marku Sep 10 '19 at 12:28
I don't know ... where you want to "short circuit" your promise chain? – Jaromanda X Sep 10 '19 at 12:34
