why is apiFetch throwing Unhandled Promise Rejection: TypeError: Object is not a function

I’m trying to diagnose a similar problem to this question, but in that case he wasn’t depending on wp-api-fetch, and … I’m pretty sure I am.

I’m getting the following error:

(full backtrace, below)

I should note that I’m new to both the REST API and ESNext/Gutenberg plugin development, so … I may be missing something really obvious, like a comma 🙂

Here’s the code:

I looked at the output of npm run start, and it seems to be including the dependencies in the build:

<?php return array('dependencies' => array('wp-api-fetch', 'wp-blocks', 'wp-components', 'wp-element', 'wp-i18n', 'wp-polyfill'), 'version' => '566e4b7cb2f100542103b2b0e25aefae');

This is being built, and docker run, on MacOS 10.15.7.

Any ideas what’s causing that error, and/or how I can further diagnose?
