Web3: insufficient funds for gas * price + value

Question

I'm trying to transfer an erc-721 token between to different wallets. They're both connected to the ropsten network, and should have sufficient funds (0.08 and 0.1 eth) to make a transaction. However, I still get an error saying that

Something went wrong when submitting your transaction: Error: Returned error: insufficient funds for gas * price + value

I've looked at the other questions regarding this, but I didn't find much useful.

Code:

async function transfer(token, tokenId) {
    const contract = new web3.eth.Contract(abi, token);

      
    try {

        const tx = {
            from: publicKey,
            to: token,
            gas: 30000,
            value: 0,
            chain: "rinkeby",
            baseChain: "rinkeby",
            hardfork: "berlin",
            data: contract.methods
                .transferFrom(publicKey, toAddress, tokenId)
                .encodeABI(),
        };

        const signed = await web3.eth.accounts.signTransaction(tx, privateKey);
        const hash = await sendTx(signed);

Answer 1

try specify the gasPrice you want to use too,

like,

'gasPrice': web3.toWei('5','gwei')

your code:

async function transfer(token, tokenId) {
    const contract = new web3.eth.Contract(abi, token);

      
    try {

        const tx = {
            from: publicKey,
            to: token,
            gas: 30000,
            gasPrice: web3.toWei('5','gwei'),
            value: 0,
            chain: "rinkeby",
            baseChain: "rinkeby",
            hardfork: "berlin",
            data: contract.methods
                .transferFrom(publicKey, toAddress, tokenId)
                .encodeABI(),
        };

        const signed = await web3.eth.accounts.signTransaction(tx, privateKey);
        const hash = await sendTx(signed);

ofcourse you would need to adjust the gasPrice according to the network
