Start by reproducing the crash at https://app.uniswap.org/#/vote and inspect the TypeScript source corresponding to static/js/78.526c1758.chunk.js, using the supplied stack trace to locate the Array.map path that calls split. Done means the vote page no longer throws this TypeError in the reported environment; the payload does not name a source file or test.
