It looks like the duplicate `Date` header is being introduced because it’s
being set at multiple layers (application + server/proxy).
According to the HTTP spec, the `Date` header should only be set once, and
most servers (Node.js, Nginx, etc.) automatically add it. If the application
code also sets it manually, it results in duplication.
**Suggested fix:**
* Remove any manual setting of the `Date` header in the application code.
* Ensure that only one layer (preferably the server/proxy) is responsible
for setting it.
For example, in Node.js:
```js
// ❌ Avoid this
res.setHeader("Date", new Date().toUTCString());
```
If a reverse proxy like Nginx is involved, you can also hide the upstream
header:
```nginx
proxy_hide_header Date;
```
This should ensure only a single `Date` header is present in responses and
resolve the issue.
