    Configuration files such as "config", "presets" and "addons" are deprecated and will be removed in Storybook 7.0.
    Read more about it in the migration guide: https://github.com/storybookjs/storybook/blob/master/MIGRATION.md#to-mainjs-configuration

    You have mixing configuration files:
    ${firstPath}
    ${secondPath}
    "${first}" and "${second}" cannot coexist.
    Please check the documentation for migration steps: https://github.com/storybookjs/storybook/blob/master/MIGRATION.md#to-mainjs-configuration
