[6.2.7] Cannot create a Story without a component set in export default

[kanidjar]

Describe the bug

An error is thrown when trying to display a story not having a component set in "export default".

To Reproduce

import { Meta, Story } from '@storybook/angular';

export default {
    title: 'HTML Elements/Buttons'
} as Meta;

export const Base: Story = args => ({
    props: args,
    template: '<button>{{content}}</button>'
});

Base.args = {
    content: 'Primary button'
};

Expected behavior

The HTML element "button" should appear on the page without any error.

@ThibaudAV is this required now? I think we are supporting the old format until 7.0?

[ThibaudAV]

normally not 🤔 yes that's what the code should do, I'll go look

🤔 I just tested with 6.2.7. and the example code I have no error :sad:

@kanidjar can you give a repo with the error reproduction?

[kanidjar]

sure @ThibaudAV , you will get it by the end of the day

[kanidjar]

@ThibaudAV : https://github.com/kanidjar/storybook

You will find the example story in apps/extranet/src/app

nx run extranet:storybook

Perfect it reproduces well the problem

Well it seems to be linked to ngcc if not executed it works perfectly ^^
Storybook does not use ivy yet but should be compatible with a workspace using it

It will be necessary to add this change earlier than expected
