Hello,
Thank you for contacting the support, and sorry for any inconvenience that might have been caused due to that.
It is normal for Rank Math to not be able to read as for this to work, you would need to apply Rank Math’s content analysis API which you can read its guide here: https://rankmath.com/kb/content-analysis-api/
With that said, this won’t affect your SEO performance as this is only the analysis report on the backend.
Hope that helps and please do not hesitate to let us know if you need our assistance with anything else.
