Lesson 14 Cannot read properties of undefined (reading 'toHexString') while deploying

[LordReya]

For some reason it's checking back on the .env. I honestly tried nearly everything. Here is the code

const { network } = require("hardhat")
const { networkConfig, developmentChains } = require("../helper-hardhat-config")
const { verify } = require("../utils/verify")
const { storeImages, storeTokenUriMetadata } = require("../utils/uploadToPinata")
require("dotenv").config()

const imagesLocation = "./images/randomNft/"

const metadataTemplate = {
    name: "",
    description: "",
    image: "",
    attributes: [
        {
            triait_type: "Jobrolevel",
            value: 100,
        },
    ],
}

module.exports = async ({ getNamedAccounts, deployments }) => {
    const { deploy, log } = deployments
    const { deployer } = await getNamedAccounts()
    const chainId = network.config.chainId

    let tokenUris
    if (process.env.UPLOAD_TO_PINATA == "true") {
        tokenUris = await handleTokenUris()
    }

    let vrfCoordinatorV2Address, subscriptionId

    if (developmentChains.includes(network.name)) {
        const vrfCoordinatorV2Mock = await ethers.getContract("VRFCoordinatorV2Mock")
        vrfCoordinatorV2Address = vrfCoordinatorV2Mock.address
        const tx = await vrfCoordinatorV2Mock.createSubscription()
        const txReceipt = await tx.wait(1)
        subscriptionId = txReceipt.events[0].args.subId
    } else {
        vrfCoordinatorV2Address = networkConfig[chainId].vrfCoordinatorV2
        subscriptionId = networkConfig[chainId].subscriptionId
    }
    log("-------------------------------------")

    await storeImages(imagesLocation)

    const args = [
        vrfCoordinatorV2Address,
        subscriptionId,
        networkConfig[chainId].gasLane,
        networkConfig[chainId].callbackGasLimit,
        networkConfig[chainId].mintFee,
        tokenUris,
    ]
    const randomIpfsNft = await deploy("RandomIpfsNft", {
        from: deployer,
        args: args,
        log: true,
        waitConfirmations: network.config.blockConfirmations || 1,
    })

    log("-------------------------------")

    if (!developmentChains.includes(network.name) && process.env.ETHERSCAN_API_KEY) {
        log("Verifying...")
        await verify(randomIpfsNft.address, arguments)
    }
}

async function handleTokenUris() {
    tokenUris = []
    const { responses: imageUploadResponses, files } = await storeImages(imagesLocation)
    for (imageUploadResponseIndex in imageUploadResponses) {
        let tokenUriMetadata = { ...metadataTemplate }
        tokenUriMetadata.name = files[imageUploadResponseIndex].replace(".jpg", "")
        tokenUriMetadata.description = `An adorable ${tokenUriMetadata.name} jobro!`
        tokenUriMetadata.image = `ipfs://${imageUploadResponses[imageUploadResponseIndex].IpfsHash}`
        console.log(`Uploading ${tokenUriMetadata.name}...`)
        const metadataUploadResponse = await storeTokenUriMetadata(tokenUriMetadata)
        tokenUris.push(`ipfs://${metadataUploadResponse.IpfsHash}`)
    }
    console.log("Token URIs uploaded! They are:")
    console.log(tokenUris)
    return tokenUris
}

module.exports.tags = ["all", "randomipfs", "main"]

That's the error:

@LordReya Please see these discussions for the same error please, if you still face the issue then let me know.

1. TypeError: Cannot read properties of undefined (reading 'toHexString') #468
2. TypeError: Cannot read properties of undefined (reading 'toHexString') #97
3. TypeError: Cannot read properties of undefined (reading 'toHexString'), when trying to run w. alchemy #356
4. Error: invalid hexlify value #470

I tried to check back on the other discussion, but it seems that it still doesn't correctly work. I kinda figured out why now.
For some reason, it doesn't let me upload to Pinata. It always fails on this exact step:

let tokenUris
    if (process.env.UPLOAD_TO_PINATA == "true") {
        tokenUris = await handleTokenUris()
        console.log("does this work?")
    }

I tried to debug and restart. Didn't work out well. The handleTokenUris() function seems fine. Maybe I'm wrong.

]
does this work?

Try to console.log out your environment variables, it looks like you have a value that isn't quite right. Usually this is a private key or something.

Or, add some console.logs in the section where you're uploading to pinata to see what's going on.

Am I missing something in my helper hardhat?

        },
    },
}

I can't find any errors in any other area to be honest. The .env and private key seems fine!
