UnimplementedFeatureError: Encoding type “struct BiddingContract.Bidder memory” not yet implemented

Question

The code is broken with the new upgrade v0.5, using Truffle v5.0.1 (core: 5.0.1)

struct Bidder {
    address bidders_address;
    uint productId;
    uint bidValue;
}

struct Product {
    uint productId;
    uint bidStartPrice;
    uint32 bidStartTime;
    Bidder latestBid;
    string productName;
    bool isAvailable;
    uint32 bidSession;

}

And mapping as

mapping(uint => Product) product;

removed the public getter venerability but still, the error is coming.

This is my full code :

    pragma solidity >=0.4.21 <0.6.0;

    import "./AucSters.sol";
    import "../libraries/SafeMath.sol";

    contract BiddingContract {

    using SafeMath for uint; 

    address admin;
    AucSters public tokenContract;
    uint256 public tokenPrice;
    uint256 public tokensSold;

    //structs
    struct Seller {
        uint256 sellerId;
        string sellerName;
        bool isValidSeller;
    }
    struct Bidder {
        address bidders_address;
        uint productId;
        uint bidValue;
    }
    struct Product {
        uint productId;
        uint bidStartPrice;
        uint32 bidStartTime;
        Bidder latestBid;
        string productName;
        bool isAvailable;
        uint32 bidSession;

    }

    mapping(address => Seller) registeredSeller;
    mapping(uint => address) public productIdToOwner;
    mapping(address => uint) public productCount;
    mapping(uint => Product) product;
    mapping(address => mapping(uint => uint)) public latestBidStore;

    //ARRAYS
    address[] public regSellers;
    Product[] public productsForSale;
    address[] public bidders;


    constructor(AucSters _tokenContract, uint _tokenPrice) public {
        //Assign an admin
        admin = msg.sender;

        // token Contract 
        tokenContract = _tokenContract;

        //Token price
        tokenPrice = _tokenPrice;
   }


}

I got the issue solved !

The array declares productsForSale also gives a by default getter as it is public, remove public and it will work

Product[] public productsForSale;

replace it by

 Product[] productsForSale;
