I created a persistent map and set a key/value pair; however when I try to later retrieve an array of values using .values, an empty array with 0 items in it is returned.

I double checked to see if the keys I'm searching for are contained, and they are.

Here's my code:
let members = new PersistentMap('memberss');

members.set(summoner , member2)

let numMembers = members.values(`satosh`, `rico`, -1, true);
