TypeError: Cannot read properties of undefined (reading 'getObjectType')

[FarhanRafid97]

why when i add @FieldResolver my app crash

@FieldResolver(() => String, { defaultValue: {} })
email(@root() user: User, @ctx() { req }: MyContext) {
if (req.session.userId === user.id) {
return user.email;
}
return '';
}

Ran into this same issue. It was due to the @FieldResolver being in the wrong place. It should be placed under the resolver (decorated with @Resolver), and not the type (decorated with @ObjectType)
