Error creating Maui app package: GraphQLDefRule rule is missing the "{ItemType}" property

Aleksandrs Maksimovs 40

I'm creating MAUI app using HotChocolate for GraphQL. Locally everything works ok (emulator, andriod device). Build run smoothly. But when I'm trying to create App archive, I'm getting error:

"Failed to create app. The "GraphQLDefRule" rule is missing the "{ItemType}" property.

What should i do? How can I fix this?

How did you archive the app? You create a keystore file and publish the APP through the .NET command line interface, right? I'm not sure how you use HotChocolate for GraphQL with MAUI, is your project a MAUI Blazor App? The error message shows the issue is related to GraphQL, would you mind sharing the detailed message? And at which archive step did you meet this error?
