Google search console complaining about Microdata

[koalabear974]

Hi!
After installing Metaknight to my kirby website, google search console started to complain about a piece a metadata added by MetaKnight. Here's the error and the piece of code:
Unparsable structured data > Reference to nonexistent item 'null'
Code:
<style itemscope itemtype="https://schema.org/WebSite" itemref="schema_name schema_description schema_image"></style>

Right now I just removed it as I'm not sure how important it is. But If someone could explain why GSC is complaining about it, and maybe how to fix it?
Thanks in advance

Had the exact same issue !

I also have the same issue. Does anybody got any news on that?

I am aware of the bug and will try to fix it in the next release. I believe it will only occur when no Meta Image has been uploaded.

As a temporary workaround add a meta image via the site-wide SEO tab.

Yes i also think it's that, cause schema_name and schema_description are added anyway. Even if these are empty. Maybe just check if there is an image and only include schema_image if true.
One other thing i just saw: I think the If-else-statement in line 35-41 is useless, cause it generates the same output. But that just as a sidenote ;)

I have same issue. @BenediktEngel is right. schema_image should be avaiblable if seo image field is not empty.
