Fetch 204 resulted in error

I got 204 No Content when GET a URI which does not exist, and I want to create it if it does not exist depends on res.status, but following code:

solidAuthClient
          .fetch(uri)
          .then(async (res: Response) => {
            // might be 401 for /private , 403 for ACL blocking , 404 for uncreated, 200 for good
            console.error('getTWContainersOnPOD() get it', uri, res.status);
            return { status: res.status, uri, text: await res.text() };
          })
          .catch(error => {
            console.error('getTWContainersOnPOD() containerTtlFiles', uri, error);
          })

only resulted in
