I am trying to trade a token (rst) for eth using the uniswap js sdk , and it keeps erroring at this line.


const trade = new Trade(route, new TokenAmount(rst, ethers.utils.parseEther(“1.0”)), TradeType.EXACT_INPUT);



UnhandledPromiseRejectionWarning: Error: Invariant failed: INPUT


has anyone encountered this before or know what’s going on?
