ReferenceErrors ID issue in JavaScript isn't getting bubbled up to the Dash Dev Tools

[chriddyp]

The error in particular was:

ReferenceError: An invalid input object was used in an `Input` of a Dash callback. The id of this object is `parcats` and the property is `selectedData`. The list of ids in the current layout is `[url, content, home-parcats, home-debug, data]` dash_renderer.v1_2_3m1580758365.dev.js:30758:13

Which occurred when I had a callback where one of the two inputs wasn't rendered on the page.

Ideally this error message should appear in the Dash dev tools.
