Internal suggestion to remove `en-US` from Mozilla urls since MDN is available in multiple languages nowadays it will automatically redirect to the viewer’s language preference. Closes [DX-2076](https://linear.app/vercel/issue/DX-2076/make-external-mozilla-links-language-agnostic-in-nextjs-docs)

title: Invalid API Route Status/Body Response
|
|
---
|
|
|
|
## Why This Error Occurred
|
|
|
|
In one of your API routes a 204 or 304 status code was used as well as sending a response body.
|
|
|
|
This is invalid as a 204 or 304 status code dictates no response body should be present.
|
|
|
|
## Possible Ways to Fix It
|
|
|
|
Send an empty body when using a 204 or 304 status code or use a different status code while sending a response body.
|
|
|
|
Before
|
|
|
|
```js filename="pages/api/example.js"
|
|
export default function handler(req, res) {
|
|
res.status(204).send('invalid body')
|
|
}
|
|
```
|
|
|
|
After
|
|
|
|
```js filename="pages/api/example.js"
|
|
export default function handler(req, res) {
|
|
res.status(204).end()
|
|
}
|
|
```
