Cannot display property of frozen object

[arkadiyk]

If I have a property like this:

  user = Object.freeze({id: "123"});

And try to display it:

User id: {{user.id}}

I am getting this error:

tracked.ts:236 Uncaught TypeError: Cannot add property Symbol(ember-object), object is not extensible

I am trying to use https://github.com/apollographql/apollo-client with Glimmer. But it fails because Apollo Client result set is frozen

Should be fixed in glimmerjs/glimmer.js#119
