How to handle provider errors? (especially network errors)

[nacknime-official]

v5.7.2
I expect that any error on "provider.getBlock(1)" will be caught, but seems Ethers don't propagate "non-ethers" errors such as networks errors and the app is just crashing.

import { ethers } from "ethers";

async function main() {
    try {
        const provider = new ethers.providers.WebSocketProvider("wss://some.non.existing.node");
        await provider.getBlock(1);
    } catch (e) {
        console.error("GET BLOCK ERR:", e); // should do that
    }
}
main().catch((e) => console.error("MAIN ERR:", e)); // don't know did that ".catch" help, but nothing changed with or without it :(

Output:

➜  yarn ts-node a.ts
yarn run v1.22.19

}

I don't understand how to handle errors with Ethers and how to built a fault-tolerant app on top of it.

Have you tried getBlock(1).catch(e=> console.log(e)) ?

Yes I have, the result is the same. Tried these:

• provider.getBlock(1).catch(e=> console.error("GET BLOCK ERR: ", e));
• await provider.getBlock(1).catch(e=> console.error("GET BLOCK ERR: ", e));
