Variable ConflictError

ConflictError: AdapterRequestErrorConstructor<ConflictError>;

Defined in: warp-drive-packages/legacy/src/adapter/error.ts:465

A ConflictError equates to an HTTP 409 Conflict response status. It is used by an adapter to indicate that the request could not be processed because of a conflict in the request. An example scenario would be when creating a record with a client-generated ID but that ID is already known to the external API.

An example use case would be to surface a conflict-specific message so the user can retry with different input:

app/routes/application.js

import { ConflictError } from '@warp-drive/legacy/adapter/error';

export default class ApplicationRoute extends Route {
  @action
  error(error, transition) {
    if (error instanceof ConflictError) {
      alert('That identifier is already in use, please choose another.');
      return;
    }

    // ...other error handling logic
  }
}
