Ember-inspector: Using Inspector (3.12.2) to view a particular Component or Data Model record fails with the following error:

[iofusion]

Ember : 3.11.1
Ember Data : 3.11.4
Inspector : 3.12.2
Chrome Version 80.0.3963.0 (Official Build) canary (64-bit)

Inspecting a Component, Data Model Record or Container results in:

Ember Inspector has errored.
This is likely a bug in the inspector itself.

This is introduced in #1035, @pzuraq @patricklx do you mind taking a look?

[rwwagner90]

@iofusion do you have an app we could reproduce this error on?

[rwwagner90]

This can be reproduced by clicking something in the data tab and trying to inspect it, as talked about in this duplicate issue https://github.com/emberjs/ember-inspector/issues/1071.

Looks like we need one more check for glimmer.value
https://github.com/emberjs/ember-inspector/blob/8b977a6287a59e1c3cc1fd37ad706fd915bd9d37/ember_debug/object-inspector.js#L914
Though is it strange that there is metal.track but not glimmer?

Edit: looks like older ember version didn't have .value function.
https://github.com/emberjs/ember.js/blob/v3.11.1/packages/@ember/-internals/glimmer/lib/utils/references.ts#L16
Any alternative?

Same here - just appeared this morning with latest update.

I am also getting the same error in the latest 3.12.2 version of the ember inspector.

@kumkanillam #1072 fixes this issue, but that update was not available in the Chrome extension store last I checked. There are instruction in this repo's readMe for installing manually.

There hasn't been a new release yet. So I guess that is normal
