The naming convention has been changed for all the interfaces:

Earlier:

:::typescript
export interface IUser extends Document {
        name: string;
        ...
}

const User = model<IUser>(DOCUMENT_NAME, schema, COLLECTION_NAME);
export default User;

Now: IUser → User and User → UserModel

:::typescript
export default interface User extends Document {
        name: string;
        ...
}

export const UserModel = model<User>(DOCUMENT_NAME, schema, COLLECTION_NAME);

Similar changes for IApiKey, IRole, IKeystore, and IBlog
