Research direction
Reproduce the swap at the supplied URL using the recorded swap state, then trace the stack from static/js/main.3e62ed90.chunk.js into static/js/9.b5edc1bf.chunk.js. Start at createUncheckedTrade, encodeSwaps, and swapCallParameters; done means the reported swap no longer crashes with an invariant failure and the regression is covered by the relevant test.
