## About the changes
What's going on is the following:
1. When a token is not found in the token's cache we try to find it in
the db
2. To prevent a denial of service attack using invalid tokens, we cache
the invalid tokens so we don't hit the db.
3. The issue is that we stored this token in the cache regardless we
found it or not. And if the token was valid the first time we'd add a
timestamp to avoid querying this token again the next time.
4. The next iteration the token should be in the cache:
54383a6578/src/lib/services/api-token-service.ts (L162)
but for some reason it is not and therefore we have to make a query. But
this is where the query prevention mechanism kicks in because it finds
the token in the cache and kicks us out. This PR fixes this by only
storing in the cache for misses if not found:
54383a6578/src/lib/services/api-token-service.ts (L164-L165)
The token was added to the cache because we were not checking if it had
expired. Now we added a check and we also have a log for expired tokens.
Some improvement opportunities:
- I don't think we display that a token has expired in the UI which
probably led to this issue
- When a token expired we don't display a specific error message or
error response saying that which is not very helpful for users
