Start by reproducing the crash at https://app.uniswap.org/#/swap with the reported swap state, then use the deployed main.b70d5d4b.chunk.js stack trace to locate the corresponding source entry point. Done means the swap page no longer throws the TypeError for this state; the payload does not identify a source file or test to run.
