Start by reproducing the crash at https://app.uniswap.org/#/vote and inspect the stack trace in static/js/78.0d57fd78.chunk.js, especially the Array.map calls around positions 1:2167–1:2906. The issue is resolved when the vote page loads without the TypeError and the underlying undefined value is handled safely.
