Lesson 15: Item Cancelled event, not updating on Moralis, no error messages

[su-adam]

ActiveItem and ItemListed work fine, however itemCancelled does not update on my Moralis Browser table

updateActiveItems script:

Moralis.Cloud.afterSave("ItemListed", async (request) => {
    const confirmed = request.object.get("confirmed")
    const logger = Moralis.Cloud.getLogger()
    logger.info("Looking for confirmed TX...")
    if (confirmed) {
        logger.info("Found item!")
        const ActiveItem = Moralis.Object.extend("ActiveItem")

        const activeItem = new ActiveItem()
        activeItem.set("marketplaceAddress", request.object.get("address"))
        activeItem.set("nftAddress", request.object.get("nftAddress"))
        activeItem.set("price", request.object.get("price"))
        activeItem.set("tokenId", request.object.get("tokenId"))
        activeItem.set("seller", request.object.get("seller"))
        logger.info(
            `Adding Address: ${request.object.get("address")} TokenId: ${request.object.get(
                "tokenId"
            )}`
        )
        logger.info("Saving...")
        await activeItem.save()
    }
})

Moralis.Cloud.afterSave("ItemCancelled", async (request) => {
    const confirmed = request.object.get("confirmed")
    const logger = Moralis.Cloud.getLogger()
    logger.info(`Marketplace | Object: ${request.object}`)
    if (confirmed) {
        const ActiveItem = Moralis.Object.extend("ActiveItem")
        const query = new Moralis.Query(ActiveItem)
        query.equalTo("marketplaceAddress", request.object.get("address"))
        query.equalTo("nftAddress", request.object.get("nftAddress"))
        query.equalTo("tokenId", request.object.get("tokenId"))
        logger.info(`Marketplace | Query: ${query}`)
        const cancelledItem = await query.first()
        logger.info(`Marketplace | CancelledItem: ${cancelledItem}`)
        if (cancelledItem) {
            logger.info(
                `Deleting ${request.object.get("tokenId")} at address ${request.object.get(
                    "address"
                )} since it was cancelled`
            )
            await cancelledItem.destroy()
        } else {
            logger.info(`No item found with address ${request.object.get("address")} and tokenId ${request.object.get("tokenId")}`)
        }
    }
})

cancel-item script

const { ethers, network } = require("hardhat")
const { moveBlocks } = require("../utils/move-blocks")

const TOKEN_ID = 1

async function cancel() {
    const nftMarketplace = await ethers.getContract("NftMarketplace")
    const basicNft = await ethers.getContract("BasicNft")
    const tx = await nftMarketplace.cancelListing(basicNft.address, TOKEN_ID)
    await tx.wait(1)
    console.log("Nft Cancelled!")
    if (network.config.chainId == "31337") {
        await moveBlocks(2, sleepAmount = 1000)
    }
}



cancel()
    .then(() => process.exit(0))
    .catch((error) => {
        console.error(error)
        process.exit(1)
    })

const TOKEN_ID = 1 this should be zero.

Hey @krakxn even when I change it to 0 there is no update on the moralis end

In ItemCancelled, spot this:

const cancelledItem = await query.first()
        logger.info(`Marketplace | CancelledItem: ${cancelledItem}`)

Replace with this: logger.info(`Marketplace | CanceledItem: ${JSON.stringify(canceledItem)}`)

In ItemListed, use my code instead (refactor variables as per your conventions):

Moralis.Cloud.afterSave("ItemListed", async (request) => {
    const confirmed = request.object.get("confirmed")
    const logger = Moralis.Cloud.getLogger()
    logger.info("Looking for confirmed TX...")
    if (confirmed) {
        logger.info("Found item!")
        const ActiveItem = Moralis.Object.extend("ActiveItem")

        // In case of listing update, search for already listed ActiveItem and delete
        const query = new Moralis.Query(ActiveItem)
        query.equalTo("nftAddress", request.object.get("nftAddress"))
        query.equalTo("tokenId", request.object.get("tokenId"))
        query.equalTo("marketplaceAddress", request.object.get("address"))
        query.equalTo("seller", request.object.get("seller"))
        logger.info(`Marketplace | Query: ${query}`)
        const alreadyListedItem = await query.first()
        console.log(`alreadyListedItem ${JSON.stringify(alreadyListedItem)}`)
        if (alreadyListedItem) {
            logger.info(`Deleting ${alreadyListedItem.id}`)
            await alreadyListedItem.destroy()
            logger.info(
                `Deleted item with tokenId ${request.object.get(
                    "tokenId"
                )} at address ${request.object.get(
                    "address"
                )} since the listing is being updated. `
            )
        }

        // Add new ActiveItem
        const activeItem = new ActiveItem()
        activeItem.set("marketplaceAddress", request.object.get("address"))
        activeItem.set("nftAddress", request.object.get("nftAddress"))
        activeItem.set("price", request.object.get("price"))
        activeItem.set("tokenId", request.object.get("tokenId"))
        activeItem.set("seller", request.object.get("seller"))
        logger.info(
            `Adding Address: ${request.object.get("address")} TokenId: ${request.object.get(
                "tokenId"
            )}`
        )
        logger.info("Saving...")
        await activeItem.save()
    }
})

Hope this works!

Hey, unfortunately the cancel Item is not working, I have even copied and pasted Patricks code from the repo and it doesn't change
