When we are making any transaction then we need gas for every transaction so how much gas I fixed to making successful transactions because sometimes the transaction is successful, and sometimes it gives me an error:
Error: Returned error: insufficient funds for gas * price + value
exports.sendTransactions = (sender_account, to_account, p_key, value ) => { console.log("sendTRansactions", sender_account, to_account , p_key , value ); var admin = sender_account; var contract_address = to_account; var tx = { from: admin, to: contract_address, gas: 184000, data: "", value: value }; return web3.eth.accounts.signTransaction(tx, p_key).then((hash) => { return web3.eth.sendSignedTransaction(hash.rawTransaction).then((receipt) => { return receipt }, (error) => { return error console.log(error); // reject(500); }) }, (error) => { return error // reject(500); }); }
