Cache get return undefined

[dondragon2]

I am using the cache manager to cache an object across processes.
await this.cache.set(objectId, { gameName: 'Test'});

Then later I try the get the object from the cache but it is undefined
const game = await this.cache.get(objectId);

This is being done from separate methods in an @Agenda

I am not sure what would be causing it to be undefined. I see the object in my mongodb and the key is correct
