State and Session store are empty in OAuth client in deno.

[technoY2K]

I've been trying to figure this out but running into a wall. The following is my StateStore implementation using Deno.Kv. During the oauth.callback function my store seem to be empty which in turn causes the following error:

Error: Cannot read properties of undefined (reading 'includes')

StateStore Implementation

export class StateStore implements NodeSavedStateStore {
  constructor(private kv) {}

  async get(key: string): Promise<NodeSavedState | undefined> {
    console.log(`Retrieving state for key: ${key}`);

    const entry = await this.kv.get(["auth_state", key]);
    return entry.value as NodeSavedState;
  }

  async set(key: string, val: NodeSavedState): Promise<void> {
    console.log(`Saving state for key: ${key}, value: ${JSON.stringify(val)}`);

    await this.kv.set(["auth_state", key], val);
  }

  async del(key: string): Promise<void> {
    console.log(`Deleting state for key: ${key}`);
    await this.kv.delete(["auth_state", key]);
  }
}

And finally the empty store in the OAuth object

sessionGetter: SessionGetter {
    getter: [AsyncFunction (anonymous)],
    store: SessionStore { kv: Kv {} },
    options: {
      isStale: [Function: isStale],
      onStoreError: [AsyncFunction: onStoreError],
      deleteOnError: [AsyncFunction: deleteOnError]
    },
    pending: Map(0) {},
    runtime: Runtime {
      implementation: { 
         requestLock: undefined,
        createKey: [Function: createKey],
        getRandomValues: [Function: randomBytes],
        digest: [Function: digest]
      },
      hasImplementationLock: false,
      usingLock: [Function: requestLocalLock]
    },
    eventTarget: CustomEventTarget { eventTarget: EventTarget {} }
  },
  stateStore: StateStore { kv: Kv {} }

@technoY2K i wrapped up stores with toDpopKeyStore as you can see here this is copied from the original node client.

as far as i cant tell, this helps with proper serialisation of the keys

Thx! This unblocked me. Could you explain what was happening when you have time? I couldn't figure this out for the life of me.
