Whenever Codeforces contests are live, their API gets slow, and as a result, my API gives FUNCTION_INVOCATION_TIMEOUT error because of the Vercel limits.

One solution to that can be a custom API cache adapter at the backend to cache codeforces API that saves the last 200 response data separately along with a time limit for temporary cache. So when data is not found in the temporary cache, it calls API, and if API gives an error or takes more than some seconds, it returns the last 200 response data.

Possible fix

API used to count problems solved: https://codeforces.com/api/user.status?handle=[username]
Function which counts it: src/pages/api/card.js

Codeforces username for which it doesn't matches: adamant, Benq, etc

Make Codeforces rank color look good in both light and dark mode .Hex code for each rank can be found here

Most probably, there is some change in the CF API that might be causing this issue.
