Stats PSDK not refreshing when stats are set server-side

[allister-beamable]

Describe the Bug

When I do await ctx.Stats.Refresh(); before interacting with the Stats collection, I expect the stats to reflect the latest and greatest values of those stats, but if the stat were changed server-side, the Stats collection contains stale data until I stop and start the app.

To Reproduce

Steps to reproduce the behavior:

1. Set a stat to a certain value.
2. Iterate over the Stats collection to print the value.
3. Use C#MS code to change the stat from step 1 to a different value.
4. Call Stats.Refresh() and iterate over the collection to print values again.
5. Observe the value of the stat.

Expected Behavior

• The value in the Stats collection should reflect the change from step 3 of the repro steps.

Actual Behavior

• The value in the Stats collection shows the old value from step 1 of the repro steps.

Sample Code

Client Code

These calls are hooked to buttons in my test harness.

private async Task SetRandomStat()
{
	var client = new BoxMicroserviceClient();
	var theNumber = await client.SetNumericStat();
	Debug.Log($"Numeric stat setting completed: {theNumber}");
}

private async Task FetchStats()
{
	var ctx = await BeamContext.Default.Instance;
	await ctx.Stats.OnReady;

	Clear();
	Debug.Log("Reading current stats...");
	await ctx.Stats.Refresh();
	foreach (var statPair in ctx.Stats)
	{
		Debug.Log($"S: {statPair.Key}={statPair.Value}");
	}
}

Server Code

[ClientCallable, SwaggerCategory("StatsTests")]
public async Task<int> SetNumericStat()
{
	var objectId = $"client.public.player.{Context.UserId}";
	var theNumber = Randomizer.Next();
	var statsRequest = new NumericStatsUpdateRequest
	{
		set =
		{
			["NUMERIC_SOMETHING"] = theNumber
		}
	};
	var uri = $"/object/stats/{objectId}";
	var response = await Requester.Request(Method.POST, uri, statsRequest, parser: s => s);
	Debug.Log($"RESPONSE: {response}");
	return theNumber;
}

Metadata

• SDK version: Beamable Unity SDK 1.19.23

• Operating System: macOS

Additional Context

The new value is reflected properly if the app is closed and reopened.

My hunch is that the Stats API is hitting its own cache when we ask to refresh. Check out the PlayerStats class.
