This route doesn’t seem to be working:

```
 /users/by-external/:external-id

```

It’s essential when using Disocurse as an SSO provider since you need to know the usernames of a user, given their external\_id. (And since usernames can change, I don’t want to manage storing them in my own database).

Any idea how to make it work? I tried appending `.json` with no luck.
