Prior to moving from Angular 11 to 12 the following error did not occur and the application was able to use the aws-sdk
library to access my S3 buckets:
./node_modules/aws-sdk/lib/event_listeners.js:572:21-44 - Error: Module not found: Error: Can't resolve 'util' in 'S:\Source\sttutter-ui\node_modules\aws-sdk\lib'
Did you mean './util'?
Requests that should resolve in the current directory need to start with './'.
Requests that start with a name are treated as module requests and resolve within module directories (S:/Source/sttutter-ui, node_modules).
If changing the source code is not an option there is also a resolve options called 'preferRelative' which tries to resolve these kind of requests in the current directory too.
BREAKING CHANGE: webpack < 5 used to include polyfills for node.js core modules by default.
This is no longer the case. Verify if you need this module and configure a polyfill for it.
If you want to include a polyfill, you need to:
- add a fallback 'resolve.fallback: { "util": require.resolve("util/") }'
- install 'util'
If you don't want to include a polyfill, you can use an empty module like this:
resolve.fallback: { "util": false }

I've tried deleting the node_modules
directory and running npm install
Search the web about this error seems to suggest that this is a webpack
issue... Based upon these conversations I'm not sure how to get this working again.
Should I switch to aws-sdk-js
even though aws-sdk
was working up and until today?
Suggestions regarding how to resolve this issue sought
Thanks!

If someone is still struggling with this issue. Please update the version of aws-sdk to 2.1174.0 or above.
npm update aws-sdk
Refer to @ElmarSchrutek comment to know about the issue. (Angular 12 moved to Webpack 5 which does not include polyfills for node.js anymore) This issue is fixed in version 2.1174 and there is no need to do anything else. For reference please visit: https://github.com/aws/aws-sdk-js/issues/3501

Angular 12 moved to Webpack 5 which does not include polyfills for node.js anymore.
To avoid adding missing polyfills on your own, use this Webpack plugin: https://www.npmjs.com/package/node-polyfill-webpack-plugin
It includes all polyfills which have been removed with Webpack 5.
Install the package and configure the Webpack plugin as described and the issue should be solved.

Try this:
rm node_modules
rm package-lock.json
npm install

The problem is related to the import of zone.js in your polyfills.ts
The old import used to be:
import 'zone.js/dist/zone';
Change to:
import 'zone.js';
And you may also need to add at the bottom of your polyfills.ts
(window as any).global = window;

I have also run into this issue, and am not sure what the official path should be, but the below has worked for me.
npm install -S util
(window as any).global.util = (window as any).global.util || require("util").util;
to your polyfills.ts
