Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client

[javaallah]

Hello guys!

When creating a user and then having him to login I got this error:

[dev.start] POST /api/users/login 200 207.582 ms - 198
[dev.start]   APIError: Not Found!
[dev.start]
[dev.start]   - error.js?:25 new ExtendableError
[dev.start]     webpack:///./src/services/error.js?:25:11
[dev.start]
[dev.start]   - error.js?:43 new APIError

[dev.start]   - index.js?:52 routes.all

[dev.start]
[dev.start] Error [ERR_HTTP_HEADERS_SENT]: Cannot set headers after they are sent to the client
[dev.start]     at validateHeader (_http_outgoing.js:503:11)

Any ideas what's wrong?
