XmlException | Data at the root level is invalid

I think I've found a bug with the XPathOnUrl formula.
I get the message"

Exception: XmlException
Message: Data at the root level is invalid. Line 1, position 1.

This is my formula:
=XPathOnUrl("https://www.jobbird.com/nl/vacatures-in-groningen/","//*[@id='related-info']",,"html")

Could somebody help me with this?

I've found the solution already.
The example is wrong on this page: https://seotoolsforexcel.com/xpathonurl/

In the line you can copy, there a 2 commas before "html")
In the gif image you see 3 ;
So you should not copy the line, but look at the image.

Thanks for spotting this, I've updated the website with an additional comma. We've added Intellisense to the regular Seotools functions which is useful for situations like this:
