Unhandled Rejections

[Jonas121]

hi,

I use ethers in a webpack package, which is running server side application.
Node version 11.15.0
"@babel/core": "^7.11.6",
"@babel/plugin-transform-runtime": "^7.11.5",
"@babel/preset-env": "^7.11.5",
"@babel/preset-react": "^7.10.4",
"babel-loader": "^8.1.0",
"ethers": "^5.0.12",
"express": "^4.17.1",
"webpack": "^4.44.1",
"webpack-cli": "^3.3.12",
"webpack-dev-server": "^3.11.0",
"webpack-node-externals": "^2.5.2"

I use strategy to include provider once per application:
var provider = new ethers.getDefaultProvider('ropsten', {infura: 'keyhere'});

I do simple step only in my application:
let filter ={
...
}
let log1 = await provider.getLogs(filter);

Code is working, provider always return data. But often application crash with an error below. What an issue could be?

A few scripts have been using the ethers default keys recently, bumping me from 4M to 20M calls per day to Alchemy and the other backends.

Does this actually cause your app to crash? Or just muddy up the logs? The application should continue working, I would think?

I am working on this now in a few directions:

• Adding further client-side throttling (should help limit the handful of people hammering my keys and help nudge them to get their own)
• Figuring out where this wayward promise is an adding a .catch to it; since the FallbackProvider will automatically fail-over
• Adding custom keys for the test suite, which is currently un-able to run so I can't publish new versions
• Rotating keys once things are ready

I do believe this is the same problem as #1208. Please see that issue for updates. :)

This should be addressed in 5.0.26. Please try it out and let me know. :)

Closing this now, as I think the problem has been resolved. If not, please re-open.

Thanks! :)
