Updating theme and brand - throwing Object(...) not a function

See original GitHub issue

how do you change the storybook logo?

I’m getting below errors after applying the theme:

import { create } from ‘@storybook/theming’;

yourTheme.js

export default create({
  base: 'light',

  brandTitle: 'My custom storybook',
  brandUrl: 'https://example.com',
  brandImage: 'https://placehold.it/350x150',
});

config.js

import yourTheme from './yourTheme';

const req = require.context('../stories', true, /\.stories\.js$/);
function loadStories() {
  req.keys().forEach(filename => req(filename));
}

addDecorator(story => (
  <ThemeProvider theme={theme}>
    {story()}
  </ThemeProvider>
));

addParameters({
  options: {
    theme: yourTheme,
  },
});

configure(loadStories, module);

I dont think the issue is resolved. I’m still seeing the same error from the console.

Can you please try to import the create function like so:

import { create } from '@storybook/theming/create';

export default create({
  base: 'light',

  brandTitle: 'My custom storybook',
  brandUrl: 'https://example.com',
  brandImage: 'https://placehold.it/350x150',
});
