Unable save data into JHipster Micro Service using Gateway UI

I set up my micro-services application with one microservice and one gateway. I generated micro service entities using $jhipster import-jdl books.jh command and entities UI in gateway. JDL file in the gateway is slightly different with options like skipServer. I used below file to generate UI for entities in gateway, and those entities generated in microservices. I was looking at all docs and issues raised by other people, but I couldn't find proper to documentation to generate Entities using Micro Service and UI for those entities in the gateway (need to specify the path of micro service in JDL file). Correct me if my syntax is incorrect. Everything went well, when open I entity page and try to save the object, it did not save it. I got following error on console.

POST http://localhost:8080/api/addresses 404 error (not found)

Books Micro Service JDL file:

entity Address
{
    streetName  String required,
    apartmentOrHouseNumber  String,
    city    String  required,
    zipcode Long    required,
    state   String,
    country String
}

entity BookCoverType
{
    coverType   String  required
}


entity Author
{
    firstName   String  required,
    lastName    String  required,
    middleName  String,
}

entity Book 
{
    bookName String required,
    bookTitle String    required,
    numberOfPages Integer   required,
}






relationship OneToOne 
{
    //Book{bookCoverType(coverType)} to BookCoverType
    Author{address(streetName)} to Address
}

relationship OneToMany 
{
    BookCoverType{book(bookTitle)} to Book

JDL documentation is not clear about this. You can use one JDL file for this and specify a microservice name in it. Remove skipServer option, because JHipster automatically does it for you. Follow this discussion on Github.

Updated JDl file:

entity Address
{
    streetName  String required,
    apartmentOrHouseNumber  String,
    city    String  required,
    zipcode Long    required,
    state   String,
    country String
}

entity BookCoverType
{
    coverType   String  required
}


entity Author
{
    firstName   String  required,
    lastName    String  required,
    middleName  String,
}

entity Book 
{
    bookName String required,
    bookTitle String    required,
    numberOfPages Integer   required,
}




relationship OneToOne 
{
    //Book{bookCoverType(coverType)} to BookCoverType
    Author{address(streetName)} to Address
}

relationship OneToMany 
{
    BookCoverType{book(bookTitle)} to Book
    Book{author(firstName)} to Author
    Author{book(bookTitle)} to Book

}
