web3.py + simpleCollectible "ContractLogicError"

[Willfromtoronto]

Hi Everybody,

I've deployed a "simpleCollection" contract from the NFT chapter and I'm trying to build the "createCollectible" transaction using web3.py but I'm getting "ContractLogicError".

   sample_token_uri = 'https://ipfs.io/ipfs/Qmd9MCGtdVz2miNumBHDbvj8bigSgTwnr4SbyH6DNnpWdt?filename=0-PUG.json'

   ###Get the abi
   with open("api/compiled_contracts/SimpleCollectible.json", "r") as file:
       simple_storage_file = json.loads(file.read())
       abi = simple_storage_file['abi']

   ##RINKEBY connection
   w3 = Web3(Web3.HTTPProvider(os.getenv("RINKEBY_RPC_URL")))
   chain_id = 4
   my_address = os.getenv("PUBLIC_KEY")
   private_key = os.getenv("PRIVATE_KEY")

   # Get the latest transaction
   nonce = w3.eth.getTransactionCount(contract_address)
   #Get the contract
   simple_storage = w3.eth.contract(address=contract_address, abi=abi)

   #Create transaction
   create_simple_collectible = simple_storage.functions.createCollectible(sample_token_uri).buildTransaction(
       {
           "chainId": chain_id,
           "gasPrice": w3.eth.gas_price,
           "from": my_address,
           "nonce": nonce,
       }
   )

The contract:

// SPDX-License-Identifier: MIT
pragma solidity ^0.6.6;

import "@openzeppelin/contracts/token/ERC721/ERC721.sol";

contract SimpleCollectible is ERC721 {
   uint256 public tokenCounter;
   
   constructor () public ERC721 ("Dogie", "DOG"){
       tokenCounter = 0;
   }

   function createCollectible(string memory tokenURI) public returns (uint256){
       uint256 newTokenId = tokenCounter;
       _safeMint(msg.sender, newTokenId);
       _setTokenURI(newTokenId, tokenURI);
       tokenCounter = tokenCounter + 1;
       return newTokenId;
   }
}

Hello @Willfromtoronto I see you are trying to deploy with plain web3 instead of brownie, so could you please share a screenshot with the whole error log ,and also share your folder structure?

This is the Cytools error, you can see info about how to solve this here.
