Error "@computed can only be used on accessors or fields..." using task decorator with modifiers

Writing code like explained in the tutorial “Version 3: Preventing Concurrency (with Tasks)” throws an exception:

Error: Assertion Failed: @computed can only be used on accessors or fields, attempted to use it with seriesAddTask but that was a method. Try converting it to a getter (e.g. get seriesAddTask() {})

My code is:

import { task } from 'ember-concurrency';
....
@task({ drop: true })
    *seriesAddTask() {
        ....
    }

I’m using ember-concurrency 2.0.3.

Writing it in this other way works fine:

@(task(function* () {
    ....
}).drop()) seriesAddTask;

I’m using npm but you have found the problem!

├── ember-concurrency@2.0.3 └─┬ ember-google-maps@3.3.0 └── ember-concurrency@1.3.0

There’s a way to solve the problem without uninstalling ember-google-maps?

With yarn, you can force it with resolutions. Not sure if there’s an npm equivalent? Otherwise, you may need to contact the upstream author to relax the dependency range or have them push a new version with v2 support.

Ok, thank you so much!
