Description

If you trigger an auth error like trying to sign in with the incorrect password, you get an error name (NotAuthorizedException for this example). If you trigger the same error again without refreshing the app,
you get a different error name in the console (TypeError) even though the network returns the same error type. Seems to be an issue with one of the amplify client packages. I attached a screenshot from my console.

Hi @MattWlodarski, Thanks for raising this. Transferring this to JS repo for better assistance.

Hi @MattWlodarski

Thanks for raising this. It seems like the error stems from this line:

amplify-js/packages/core/src/errors/AmplifyError.ts

Lines 29 to 31 in f1613e2

	// Hack for making the custom error class work when transpiled to es5
	// TODO: Delete the following 2 lines after we change the build target to >= es2015
	this.constructor = AmplifyError;

However, we cannot reproduce this issue. I notice you are using zonejs from the stack trace. It may cause unwanted effect on the this scope. Can you try if you can still reproduce this issue without zone.js?
