Group Filter URL Parameters

[MarcoConopio2]

I am trying to activate the group filter in my webapp via URL parameters.I have this Group Filter.

Hence my url is like this 

https://<your portal URL>/apps/webappviewer/index.html?id=<Item ID>&groupfilter={“Year”:[“2023”]}

However it doesnt seem to work and my webapp is not loading at all

Any idea why is it not working?

@MarcoConopio2  Just verified this on my end in the ArcGIS Online edition of Web AppBuilder and it seems to be working as expected, here's an example URL parameter.

At first glance, I'd say make sure the quotes are " and not “ ?

If that doesn't resolve the issue, are you using ArcGIS Online or Enterprise Portal, or perhaps the developer edition? Any special security setup on your server?
