Current behavior

When exporting an @ObjectType() class, compiling and publishing to my npm repository I'm no longer able to import that class and use it as a type in my resolver.

When the schema tries to generate the following error is thrown (error from the reproduction repository)

(node:20308) UnhandledPromiseRejectionWarning: Error: Cannot determine a GraphQL output type for the "failedQuery". Make sure your class is decorated with an appropriate decorator.

Expected behavior

As with v6 when using type-graphql, the class should be imported and the type should be added to the generated schema.

Can you test with @nestjs/graphql@next (next tag) please?

@kamilmysliwiec I'm thrilled to say that the next version seems to resolve my problem!
