Firestore : No properties to serialize found on class

Note:

Please don't mark this question as a duplicate as I have already gone through similar questions and their answers.

Error :

proguard-rules.pro:

-assumenosideeffects class android.util.Log {
    public static *** d(...);
}

# Add this global rule
-keepattributes Signature

-keep class android.support.v7.widget.RecyclerView { *; }

# Keep custom model classes
-keepclassmembers class com.mypackage.model.** { *; }
-keep class com.mypackage.model.** { *; }
-keep class com.mypackage.util.** { *; }

Using the mapping file, I found the error to be caused by the following model class:

User.java:

package com.mypackage.model;

import java.io.Serializable;

public class User implements Serializable {

    //  Data
    private Long phone;
    private String uid, name, mail, apartmentName, doorNo;
    private UserType userType;

    public User() {
        userType = UserType.USER;
    }

    public Long getPhone() {
        return phone;
    }

    public void setPhone(Long phone) {
        this.phone = phone;
    }

    public String getUid() {
        return uid;
    }

    public void setUid(String uid) {
        this.uid = uid;
    }

    public String getName() {
        return name;
    }

    public void setName(String name) {
        this.name = name;
    }

    public String getMail() {
        return mail;
    }

    public void setMail(String mail) {
        this.mail = mail;
    }

    public String getApartmentName() {
        return apartmentName;
    }

    public void setApartmentName(String apartmentName) {
        this.apartmentName = apartmentName;
    }

    public String getDoorNo() {
        return doorNo;
    }

    public void setDoorNo(String doorNo) {
        this.doorNo = doorNo;
    }

    public UserType getUserType() {
        return userType;
    }

    public void setUserType(UserType userType) {
        this.userType = userType;
    }
}

UserType.java:

package com.mypackage.model;

public enum UserType {
    USER, ADMIN, DELIVERY
}

The above error was resolved after doing the following:

Clean and rebuild project.
Removing all proguard rules.
Adding @Keep in each model class beginning.
