The error is caused by the dynamic import in this line https://github.com/Uniswap/widgets/blob/main/src/i18n.tsx#L82

According to the doc, this error can be eliminated by adding a special comment

const catalog = await import(/* webpackPrefetch: true */ `./locales/${locale}.js`)

https://webpack.js.org/guides/code-splitting/#dynamic-imports

Expected Behavior No warnings at compile time
