Why do I get this error only when my application is in production? - express

Question

I am developing an application with NuxtJS and SSR, I am also using axios and auth modules. Everything works perfectly in localhost, but later when I upload the application to the host (Vercel) and try to log in, it gives me the 405 error. Does anyone know why this happens? The server is created with express
Error: Request failed with status code 405
