aws-sdk: crash after updating from angular5 to angular6

Question

I just updated to Angular 6.0 from Angular 5.2, my code now break with this error:

core.js:1601 ERROR Error: Uncaught (in promise): ReferenceError: global is 
not defined

anybody knows the problem? I have tried ng update but seems like aws-sdk-js doesn’t provide the schematics for updating

Answer 1

Add following to polyfills.ts

// aws-sdk requires global to exist
(window as any).global = window;

Answer 2

There is a workaround until this issue is resolved,

try adding in your index.html head tag the following

<script>
  if (global === undefined) {
    var global = window;
  }
</script>
