For singleton types that have no identifier, you can set `keyFields: []` to ensure they're still persisted in the cache.

keyFields: []to ensure they're still persisted in the cache.I just wasted an entire day trying to figure out how to configure the InMemoryCache so it would persist my singleton query types. I found this comment, which finally solved the issue for me, so I think it belongs in the documentation. I'm happy to write more or move this elsewhere in the documentation if you feel it's appropriate, but I want to help others in the future :)
