Research direction

Start at the swap entry point at https://app.diffusion.fi/#/swap and reproduce the reported state with INPUT currencyId EVMOS and an empty OUTPUT currencyId. Trace the minified call in static/js/main.6cd77a5b.chunk.js through the reported Array.sort location; done means the swap page no longer throws the undefined-name error for this state.
