What's Wrong?

Whenever i use claude code, i'm using 2.1.117. I'm getting Context limit reached, whenever i try compacting, i get: ❯ /compact
⎿ Error: Error during compaction: API Error: Extra usage is required for 1M context · run /extra-usage to
enable, or /model to switch to standard context

If i run /context, this is my output:
/context
