Star-rating plugin error

I’ve a problem with the plugin. On all sub-pages it’s working correctly and the stars are displayed correctly, but on the homepage I get an error:

…/user/themes/striped/templates/partials/blog_item.html.twig 112

It’s the theme Striped and this block:
{% if page.header.continue_link is sameas(false) %}

{{ page.content }}

{% if not truncate %}
{% set show_prev_next = true %}
{% endif %}
{% elseif truncate and page.summary != page.content %}

An exception has been thrown during the rendering of a template (“array_merge(): Argument #1 is not an array”).

I didn’t make changes to the settings in the star-ratings.yaml. Any idea?

I run the site locally, so I’m not able to show you the error online.
