 rateLimiter.get always returns `null`
I am trying to implement a check (not consume) for current rate limits, however `rateLimiter.get` always returns `null` even though I can clearly see entries in the database with points.

```js
const rateLimiterKey = rateLimiter.getKey(user.id);
  await rateLimiter.get(rateLimiterKey).then(rateLimiterRes => {
  console.log(rateLimiterRes) // Always returns null
  // .. Do stuff
})
```
in DB i have
```
key			points		expire
rtlmtrflx:123456	4		1699638168782
```
