Unit tests failing with Node.js 16

[qhanam]

GitHub is updating Node.js to version 16 in all OS images.

Several unit test suites and unit tests fail when run with Node.js 16:

• Jest worker encountered 4 child process exceptions, exceeding retry limit
  • CognitoIdentityClient.test.ts
  • BeaconHttpHandler.test.ts
  • StsClient.test.ts
  • Authentication.test.ts
  • CommandQueue.test.ts
• when a TypeError is thrown then the plugin records the name, message and stack

To reproduce, run npm run test with Node.js 16.

[thankyouveryfun]

I could try to solve this if nobody is on it

Thanks for the offer! I picked this up since it is a CI blocker.

More issues to come...

Just to confirm, we wouldn't have expected the CI to automatically break since we install a node version, right?

Of course good to fix the build on newer node (and probably can run CI on multiple nodes) but just checking

Ah yes you are correct, so the node upgrade is moot. Regardless, this is a bit of a blocker for anyone onboarding using node 16.
