Contract Add Error on Cis2-MarketPlace

As shown in the picture above this error occurred when I was trying to add my nft on the marketplace with the error code -1 it says that the parameters were wrong in some way but I tried different option yet still came to the conclusion that these parameter formats were correct yet still I received the error telling me that it couldn’t parse the parameters. Please help resolve this issue

AddFunction Code :

#[receive(
    contract = "Market-NFT",
    name = "add",
    parameter = "AddParams",
    mutable
)]
fn add<S: HasStateApi>(
    ctx: &impl HasReceiveContext,
    host: &mut impl HasHost<ContractState<S>, StateApiType = S>,
) -> ContractResult<()> {
    let params: AddParams = ctx
        .parameter_cursor()
        .get()
       .map_err(|_e| MarketplaceError::ParseParams)?;

    let sender_account_address: AccountAddress = match ctx.sender() {
        Address::Account(account_address) => Option::Some(account_address),
        Address::Contract(_) => Option::None,
    }
    .ok_or(MarketplaceError::CalledByAContract)?;

    let token_info = TokenInfo {
        address: params.nft_contract_address,
        id: params.token_id,
    };

    ensure_supports_cis2(host, &params.nft_contract_address)?;
    ensure_is_operator(host, ctx, &params.nft_contract_address)?;
    ensure_balance(
        host,
        params.token_id,
        &params.nft_contract_address,
        sender_account_address,
        params.quantity,
    )?;

    host.state_mut().list_token(
        &token_info,
        &sender_account_address,
        params.price,
        params.royalty,
        params.quantity,
    );
    ContractResult::Ok(())
}
