Ethereum NFT Marketplace Boilerplate Error


I’m a commercial artist and designer working with a non-profit on a collection and platform that we hope will provide funding for, and raise awareness about their efforts.

I’m not a programmer and I don’t know javascript beyond what I’ve deduced from the various tutorials I’ve followed. I am over my head for sure, just hoping for some guidance or hints.
I am working on the NFT Marketplace tutorial on GitHub:

I have the contract deployed via Remix.
When I access the NFTMarketPlace page, I am getting an error . . .

In the Chrome console I get:
Failed to load resource: the server responded with a status of 400

In the Moralis Dashboard log I get:

2022-03-01T18:46:25.411Z - Error: Invalid hex number
    at fetch (/moralis-server/lib/cloud-code/plugins/helpers/apiUtils.js:179:26)

2022-03-01T18:46:25.393Z - Failed running cloud function getAllTokenIds for user undefined with:
  Input: {"chain":"0x89","address":"explore","limit":10}
  Error: {"message":"Invalid hex number","code":141}

I’ve seen a couple of other posts about this same issue, but couldn’t comprehend the solution.


Someone posted an issue on GitHub that seems like it could be relevant?

“Similar error in NFTBalance component and NFTTokenIds component.
const contractABIJson=JSON.parse(contractABI), this causes an error in both components because the abi is not supposed to be parsed”
