Hi
I had the same problem. I have used the Schema Markup Generator of https://technicalseo.com/tools/schema-markup-generator/ and tested it on https://search.google.com/test/rich-results to check if the markup is valid. The markup I created is focussed on local business. For now I have put the markup in the advanced coding part of my homepage. It solved the error for my homepage, but I still get same error for different pages.
Do you maybe now if you should put the markup in de code injection for each single page or should I put in the advanced code injection of the footer or header?
Kinde regards,
Niels
