hey guys , please why when i deployed my express api to railway the post req is not working , it works as expexted from my localhost , but when i use railway url i get html res with this body

    <pre>Cannot GET /upload</pre>

only get res is working

this is some of my code maybe it helps :

const express = require("express");

require("dotenv").config();

const app = express();

app.use(express.json());

app.post("/upload", upload.single("file"), async (req, res) => {

try {

// Upload the file to the cloud

} catch (error) {

// console log the error and return status 500

}

});

const port = process.env.PORT || 3000;

app.listen(port, () => {

console.log("working!!");

});
