It may be a particular module or plugin creating the error. I'd personally advise re-installing the Prestashop core files in case you haven’t already.

Make sure to check the status code from the reaction and https://addons.prestashop.com/de/seo-suchmaschinenranking-optimization/31857-automatische-google-rich-snippets-json-ld-opengraph-seo.html
