DS.AdapterError.extend fails

based on documentation https://emberjs.com/api/data/classes/DS.AdapterError.html I am trying to duplicate.

my code : 

  import DS from 'ember-data';

  export default DS.AdapterError.extend({ message: "Down for maintenance." });

but I just get errors

Uncaught TypeError: _emberData.default.AdapterError.extend is not a function

has anyone extended this error object? I ma truly just capturing 401,403 errors that happen during the ember-data transaction. I wanted to use some custom errors.

Solution

  • It looks like you hit a snag in the documentation. The code you are wanting to use is actually behind a feature flag which will enable that functionality ... Apparently the build tools for API docs aren't handling that right (or the docs weren't feature flagged properly).

    See https://github.com/emberjs/data/blob/master/FEATURES.md and https://github.com/emberjs/data/blob/v2.12.0/addon/adapters/errors.js#L11 for further details.
