New request with axios if the first does not work

i made this function that makes a request to the API based on the past parameters, only if it returns an error i want a NEW REQUEST to be made only by changing the value of the URL that i pass, removing a parameter, it's possible? Below is what i tried but failed

try {
    const URL = 'http://api.evoximages.com/api/v1/vehicles?make='+make+'&model='+model+'&year='+year+'&pid=2&ptid=41&body='+body;
        let res = await axios.get(URL);
        
        if (res.data.statusCode == 404) {
            URL = 'http://api.evoximages.com/api/v1/vehicles?make='+make+'&model='+model+'&year='+year+'&pid=2&ptid=41';
            res = await axios.get(URL);
    
            return res.data.data;
        } else {
            return res.data.data;
        }  
    } catch (err) {
      return err;
    }

I realized that I can't get the statusCode because they are falling in Catch(err), so how can I do to make a new request if the first is not accepted?

SOLUTION:

try {
      const URL = 'http://api.evoximages.com/api/v1/vehicles?make='+make+'&model='+model+'&year='+year+'&pid=2&ptid=41&body='+body;
      let res = await axios.get(URL); 
      return res.data.data;
     
    } catch (err) {
      try { 
           // New request
           const URL = 'http://api.evoximages.com/api/v1/vehicles?make='+make+'&model='+model+'&year='+year+'&pid=2&ptid=41';
           let res = await axios.get(URL);
           return res.data.data;
      } catch (err) {
           return err;
      }
    }

If it only what you describe of one request being failed you want the second to start then call the second one inside the first catch

try {

    const URL = 'http://api.evoximages.com/api/v1/vehicles?make=' + make + '&model=' + model + '&year=' + year + '&pid=2&ptid=41&body=' + body;

    let res = await axios.get(URL);

    return res.data.data;

} catch (err) {

    console.error(err);

    try {
      URL = 'http://api.evoximages.com/api/v1/vehicles?make=' + make + '&model=' + model + '&year=' + year + '&pid=2&ptid=41';
      res = await axios.get(URL);

      return res.data.data;
    }
    catch(error){
      console.error(error);
    }
}

if you have many urls, and you want to keep requesting if the first failed and keep goind until the end you can do something like this


const urls = [
    'http://api.evoximages.com/api/v1/vehicles?make=' + make + '&model=' + model + '&year=' + year + '&pid=2&ptid=41&body=' + body,
    'http://api.evoximages.com/api/v1/vehicles?make=' + make + '&model=' + model + '&year=' + year + '&pid=2&ptid=41',
    'any more urls...'
];

async function callingUrlsInSequence(urls) {

    let i = 0;

    while (i < urls.length) {
        const url = urls[i];

        try {
            const response = await axios.get(url);
            // break the loop and return from function if the request succeed
            return response;

            // otherwise we keep looping...
        } catch (error) {

            console.error('The Url: ' + url + ' Failed!')
            continue;

        } finally {
            i++;
        }
    }
}
