Start by reproducing the swap at https://app.uniswap.org/#/swap with the supplied INPUT and OUTPUT state, then search the codebase for the exact “Invalid WETH contract” message and compare it with the minified stack trace. Done means identifying why this WETH address is rejected and verifying that the same swap state no longer crashes.
