Interacting with a Smart Contract, Web3 issue. I'm running into an issue connecting a React frontend to a smart contract. specifically with the Contract methods of web3.eth in web3 1.0. I'm using the smart contract for simple storage from the Solidity docs. Here are the relevant lines in the frontend:Error: Returned error: VM Exception while processing transaction: revert Exactimation confirmed 🚀.

Because the router contract cannot anticipate this trailing transfer when calculating the invariant, the transaction will either revert, or partially succeed by sending the primary transfer but breaking the pool upon the trailing transfer.I'm using the build files from truffle to get the ABI and deployed address for a contract, and I run web3.eth.contract(abi, address); to get a Contract object.
