If the folder already uploaded, how do you edit the ipfs CID on json file, because you get the CID AFTER you upload it to Pinata

{
  "name": "sloppy-steve",
  "description": "A drawing of sloppy steve",
  "image": "ipfs://YOUR_ASSET_CID", //This One
  "attributes": [
    {
      "beard": "",
      "rarity": 0.5
    }
  ]
}

Why does it not show the image before it is minted? Is it going to display the image before they are minted if I upload my collection to the opensea mainnet?

At hardhat.config.js step of the web tutorial, it's missing the hardhat-waffler import:

require("@nomiclabs/hardhat-waffle");

Without that line, it will through an error:

TypeError: Cannot read property 'getContractFactory' of undefined

when i try to load the page i get this error: index.ts:225 Uncaught (in promise) Error: call revert exception (method="count()", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.5.0) and this one
Uncaught (in promise) Error: call revert exception (method="isContentOwned(string)", errorArgs=null, errorName=null, errorSignature=null, reason=null, code=CALL_EXCEPTION, version=abi/5.5.0)

i dont know how to fix this and also dont know what the causes the problem

I know that it is possible to open the metamask app directly from the button without copying and pasting the link into the metamask browser because other collections do this. do you know how to do it?

Hello,

First of all thanks for this amazing introduction to web3 and the work you've put in !

I tried do recreate what you did but encountered an error, and so I decided to clone your repo to try it out and I have the same issue.

When I want to mint a token, Metamask opens but the transaction failed with this error in my Hardhat node server:
Trying to send a raw transaction with an invalid chainId. The expected chainId is 31337

And this error on the front part:

{
  code: -32603,
  message: `"[ethjs-query] while formatting outputs from RPC '{"value":{"code":-32603,"data":{"code":-32602,"message":"Trying to send a raw transaction with an invalid chainId. The expected chainId is 31337"}}}'"`
}

In the code, I've only changed the CID to point to my Piñata file and removed the matic network configuration in the Hardhat config because I want to test locally.

Do you know why it does this ?

Thanks in advance,

Félix
