@tianji6666 Sorry for my delay. I've been away from github for a while. Straight to your question, you needed to deploy your contract in the bsc mainnet and you must have had the json key networks[97].address in your builded json file. It seems like it was not fille out and type was undefined when it tried to read at address in json file. Please make sure that you have deployed the Flashswaptest.sol contract and deploying generated a json file in the appropriae path.

const swapcontract = new web3.eth.Contract(
    Swapcontract.abi,
    Swapcontract.networks[networkId].address
);
