Research direction
Start by reproducing the reported swap URL and state, then trace the swapCallParameters, encodeSwaps, and createUncheckedTrade entry points named in the stack trace. Done means this input no longer crashes with an unhandled “Invariant failed” error, with coverage added if an existing test location is identified.
