How to do error handling with ethers.js and uniswap sdk?

[mormone]

How could I handle 'Error: could not detect network (event="noNetwork", code=NETWORK_ERROR' ? I would like to catch the error. For example:

const XToken = await (async () => {
try {
return Fetcher.fetchTokenData(chainId, tokenAddress, provider);
} catch (error) {
console.log('no-network errror. not thrown here', error);
}
})();

this is in a node.js app. If I there is no internet connection I get this error. But it is not catched inside my catch block.
