`Uncaught TypeError: Object(...) is not a function` when adding Core blocks

[iandunn]

I'm trying to add some Core blocks, so that I can test a custom format I'm working on. I copied parts of the example, and it loads them. The Card tab has all the info, but I get an error when I click on the Example or Editor tabs.

The only things in my .blockbook/index.js are:

import { registerBlockType } from 'blockbook-api';

// Register BlockBook blocks.
const coreBlocks = [
    'core/paragraph',
    'core/pullquote',
    'core/quote',
];
coreBlocks.forEach( ( block ) => registerBlockType( block ) );

Uncaught TypeError: Object(...) is not a function

Am I doing something wrong?

No that looks good but I've not touched the project in a while and updated packages from Core can break it. So I'm not really sure what's happening here.

In general most of the issues comes from the fact that the tool itself uses @wordpress packages and the blocks also can use these, so resolving to the right version is often very hard.
