Does anyone know what this error means and how can I fix this?

This is the code that I'm using:

this.createView('record', 'views/record/list', {
collection: this.wait(this.loadCollection()) ,
type: 'listSmall',
});​

async loadCollection() {
this.collection = await this.getCollectionFactory().create('User');
await this.collection.fetch();
}​

You need to load the collection collection asynchronously first. Then pass it to the list view. You can create a separate async method that will load the collection instance, and then creates the list view (asynchronously too). Then use this.wait(...) on this method in the setup method.
