I am trying to check if my Post purchase app extension is in use by using the followign Graphql query -
app_in_use_query = client.parse <<-'GRAPHQL'
However in response I get the error message - Field 'isPostPurchaseAppInUse' doesn't exist on type 'App'.
This query is documented in the Shopify docs here - https://shopify.dev/apps/checkout/post-purchase/ux-guidelines-post-purchase-offers#post-purchase-app...
Does anyone know how to correctly run this query or have I found a bug in the Shopify API?
I am getting this message as well and am using 2010 API version. It works in Graphiql when testing in Shopify.
