Error in BN package when building with my own deployed smart contract

[Shane-Neeley]

Wasn't getting this at first. Trying to go to http://localhost:8000/en/?hero=7 .. Any idea what this is about?

UPDATE: this was happening after I built using my own deployed contract, not the v2.tenk.testnet. Which contract should I deploy, the one in the frontend code?

[Shane-Neeley]

I guess my main question is, what do I deploy to testnet to test this out? There's src/near/contracts/tenk.ts in the frontend code, but you also have contracts in https://github.com/TENK-DAO/tenk/tree/main/contracts/tenk ... both Rust and TypeScript.

Regarding the error: This error will come up with “price” is missing from the JSON when initing the contract. It lets you do that because the init function takes an Option type for the sale key:

    pub fn new_default_meta(
        owner_id: AccountId,
        metadata: InitialMetadata,
        size: u32,
        sale: Option<Sale>,
    ) -> Self {
        Self::new(owner_id, metadata.into(), size, sale.unwrap_or_default())
    }

But the Sale itself has one mandatory key that’s easy to miss, price :

pub struct Sale {
    pub royalties: Option<Royalties>,
    pub initial_royalties: Option<Royalties>,
    pub presale_start: Option<TimestampMs>,
    pub public_sale_start: Option<TimestampMs>,
    pub allowance: Option<u16>,
    pub presale_price: Option<U128>,
    pub price: U128,
    pub mint_rate_limit: Option<u16>,
}

(which, on top of all that requires a String, not a U128, because U128 isn’t a primitive, it’s a macro.)
