Populate select widget with fetched options

[tpluscode]

I would like to fetch the options for a select widget from an API.

I could build a custom widget from the ground up like I did for another field using Typeahead but in this case I could just fetch all values.

Is it possible with the default widget?

For now I copied much of decap's select widget but it seems unnecessary. Problem is that when I tried to actually reuse it, I get this cryptic error I was unable to figure out

Error: Element type is invalid: expected a string (for built-in components) or a class/function (for composite components) but got: object. Check the render method of VocabularySelectComponent.
