ember-polyfills.deprecate-assign deprication in Ember 4.4

[usamahamed]

I am currently upgrading Ember version to 4.4 and now i get this depreciation with id ember-polyfills.deprecate-assign

Seems it comes from ember-simple-auth/addon/utils/assign.js

More info: https://deprecations.emberjs.com/v4.x/

versions
ember-simple-auth: 4.2.2
ember-source and ember-cli: 4.4.0
npm: 16.14.0
node: 8.3.1

In 4.2.0 we've released a fix for that which should use Object.assign instead of the polyfill when available.

Is the deprecation happening inside some older browser by any chance?

@BobrImperator You're right, looks like it was because of this issue ember-cli/ember-fetch#707

Sorry for my late reply, vacations time 😆
