app: Module parse failed: Unexpected token (50:40)
app: File was processed with these loaders:
app: * ../../../node_modules/ts-loader/index.js
app: You may need an additional loader to handle the result of these loaders.
app: | export const Layout = (props) => {
app: | const regionsResults = useQuery(regionsQuery, { fetchPolicy: 'cache-first' });
app: > const regions = regionsResults.data?.regions ?? [];
app: | const userItem = useQuery(usersProfileQuery, { fetchPolicy: 'cache-first' });
app: | const handleOnClick = (selected) => props.history.push(selected.key);
