Invalid arrayify value, set uri for erc1155

Hello,

I am getting this error
(argument=“value”, value=“https://ipfs.moralis.io:2053/ipfs/Qmc1TvL5RwDQhFUTNRBv7V5WVSeoWjs87RypJvZ1qfGJrU”, code=INVALID_ARGUMENT, version=bytes/5.4.0)

Here’s my code

        const encodedFunction= web3.eth.abi.encodeFunctionCall({
          name:"mint",
          type:"function",
          inputs:[{
            type:'address',
            name:'account'
          },{
            type:'uint256',
            name:'id'
          },{
            type:'uint256',
            name:'amount'
          },{
            type:'bytes',
            name:'memory data'
          }
        ]
      },[ethereum.selectedAddress,100,1,_uri])

        const transactionParameters= {
          to:contract,
          from:ethereum.selectedAddress,
          data:encodedFunction
        }
        const txt = await ethereum.request({
          method:'eth_sendTransaction',
          params:[transactionParameters]
        });

        resolve(txt)

Here’s the contract function

    function mint(address account, uint256 id, uint256 amount, bytes memory data)
        public
        onlyRole(MINTER_ROLE)
    {
        _mint(account, id, amount, data);
    }

This is for an erc1155, I used the example on this youtube tutorial

it looks like you receive bytes as parameter, in the tutorial it was string as parameter.
Somehow you’ll have to convert that string to bytes if you want to send it as bytes as the mint function expects.

#3

the tutorial is for erc721, i’m using erc1155

Ok, in erc1155 it may be a different way to set the url, setBaseMetadataURI would set a base uri and uri would generate an uri based on base uri and id.

#5

I’m new to this, how would I redo the code with your answer?

#6

converting it using web3 seems to work, but there’s an error in the contract still that I can’t seem to fix

web3.utils.asciiToHex(_uri)

#7

The name of the parameter is not “memory data”. It is only “data”. memory is a type and not the name.

So, you have to do this -
const encodedFunction=

web3.eth.abi.encodeFunctionCall({
          name:"mint",
          type:"function",
          inputs:[{
            type:'address',
            name:'account'
          },{
            type:'uint256',
            name:'id'
          },{
            type:'uint256',
            name:'amount'
          },{
            type:'bytes',
            name:'data'
          }
        ]
      },[ethereum.selectedAddress,100,1,_uri])

Hope this helps.

Also, it is advisable to always pick the contract method objects from ABI itself to avoid human error.

Happy BUIDLing!

I think that you’ll have to take a look at the erc1155 standard to understand what is going on there.
