It makes sense with former, as there are race conditions b/w miners and increasing gas price may help, but why it happens on my private net where transactions are rare and mining difficulty is low?
I use web3js send method to send 2 types of transactions:
/** executes contract method by creating transaction * @param {string} from - payer address * @param {string} to - payee address * @param {int} amount - number of tokens * @param {string} type - transaction type */ transferTokens(from, to, amount, type) { if (type === 'transfer_to_admin' || type === 'transfer_from_user') { return this.contract.methods.transferFrom(from, to, amount).send({ from }) .catch((err) => { logger.info(err); return Promise.reject(err); }); } if (type === 'transfer_from_admin') { return this.contract.methods.transfer(to, amount).send({ 'from': this.coinbase }) .catch((error) => { logger.info(error); return Promise.reject(error); }); } } where transfer and transferFrom are Solidity functions implemented by ERC20 standard.
Anyone knows how to avoid/handle this error?
