I could not find any structured data on this page, so I am not sure where Google gets this information from.

What are Unparsable Structured Data Errors? Google is cracking down on bad structured data and they are letting you know they found some on your website. They are syntax errors within your structured data. In other words, the structured data is that is already on your site is formatted improperly.

No global identifier provided (e.g. gtin, mpn, isbn) The warning is about structured data
According to the rich results test there is indeed a warning
'No global identifier provided (e.g. gtin, mpn, isbn) (optional)'
see https://search.google.com/test/rich-res ... YuVE3Ivqkg for more info
This is optional so not required. You might ignore it if it is not applicable to your products / situation.

You might check https://developers.google.com/search/do ... es/product if you need more info

Since Google can’t read it properly, they are warning you about it. Basically “parse” is geek for read.
When Google reads your structured data, they need to be able to understand it.
If Google can’t “parse” or read structured data this presents a problem because they can’t use it.
If Google can’t use your structured data, they might not be able to award you with “rich snippets” or show the correct info for your products in search results or ads.

Lastly I myself am confused about what the site is about forget about google. I see menu under images cards without header tags and others. According the the seo report I checked here is the link https://seositecheckup.com/seo-audit/ww ... france.com analysis the site has lots and lots of SEO issues so this is just 1 warning from google other warnings are coming soon.
