Research direction
Reproduce the swap URL and state, then trace the reported createUncheckedTrade, encodeSwaps, and swapCallParameters calls in the source. Determine why this input produces the invariant failure; done means the swap no longer crashes for the reported case and the behavior is covered by an appropriate test.
