Answer 1

As mentioned in the comments, some part of the exception is missing. However, the issue can also be found in the first line of the stacktrace:
org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'userRepository
And:
org.springframework.data.mapping.PropertyReferenceException: No property lastName found for type User!
So, you should check your UserRepository, since you have a query or a method name that references a property called lastName even though you don't have one in your User entity.
