Secure Real Time Multiplayer Game - Failed 4 last test cases

[japananh]

Tell us what’s happening:
I saw all headers are corrected on my solution links but 4 final tests were failed.

Result from brower’s network is correct for all requests as below

This is my code

// server.js
const helmet = require("helmet");
const nocache = require("nocache");

app.use(
  helmet({
    noSniff: true,
    xssFilter: true,
    hidePoweredBy: {
      setTo: "PHP 7.4.3",
    },
  })
);

app.use(nocache());

package.json

I found the FCC’s test cases here. I tried to copy and run them on local and I passed all but still failed 4 tests when I submitted.

What is my error? Any hint to fix it?
