vite config proxy config don't rewrite path - vuejs3

Question

I have a cors issue in my development with vue3 & vite, so I create a proxy config in my vite.config.js
import { defineConfig } from 'vite'
import vue from '#vitejs/plugin-vue'
import { resolve } from 'path'
export default defineConfig({
plugins: [vue()],
resolve: {
alias: {
'#': resolve(__dirname, 'src'),
},
},
server: {
proxy: {
"/api": {
target: "https://###.com",
changeOrigin: true,
secure: false,
rewrite: (path) => path.replace(/^\/api/, ""),
},
}
}
})
when I use in my app my method:
createPayment() {
const url = "/api/webhook/###";
let formData = new FormData();
formData.append("firstName", this.first_name);
formData.append("lastName", this.last_name);
formData.append("email", this.email);
formData.append("phone", this.phone);
formData.append("cardNumber", this.c_number);
formData.append("cardExpiration", this.c_EXP);
formData.append("cardCCV", this.c_CVC);
const request = new Request(url, {
method: "POST",
body: formData,
headers: {
accept: 'application/json',
contentType: "application/json;charset=UTF-8",
AccessControlAllowOrigin: '*'
},
});
fetch(request)
.then(result => console.log(result))
.catch(error => console.log('error', error));
},
The Post all ways send from localhost, I can't understand why?
I make the config for change '/api' to 'https://###.com' ?
My Log:
Response {type: 'basic', url: 'http://localhost:3000/api/webhook/####', redirected: false, status: 404, ok: false, …}
