Demonstrates a problem with Open API generation using Microsoft.AspNetCore.OpenApi The project generates OpenApiGenerationNullability.json. In that document a list of AmTranslation objects is used in 2 different classes. In that case it seems that the reference generated in the second class is not correct. In AmEnvironment the reference is: "$ref": "#/components/schemas/#/properties/application/properties/translations/items" But it should be: "$ref": "#/components/schemas/AmTranslation" (as it is correct in AmApplication)
Seems this is already reported and should be fixed in 9.0.4: dotnet/aspnetcore#60381
