How do you catch network errors from subscriptions? [6.0.3]

[ng-tony]

Im currently using a fallback provider with BSC providers. I'm keeping track of the block number using provider.on("block", console.log)

When the provider will runs into some error, the whole script will crash. Is there some way to handle the error?

const mn = async () => {
  const provider = new ethers.FallbackProvider([
    {
      provider: new ethers.JsonRpcProvider('https://bsc-dataseed1.defibit.io/'),
    },
    {
      provider: new ethers.JsonRpcProvider(
        'https://bsc-dataseed2.ninicoin.io/',
      ),
    },
  ]);
  provider.on("block", console.log);
};
