Hello,
Thank you for contacting Rank Math and bringing your concern to our attention.
We’ve tested the URLs you shared using Google Rich Results tool, but there’s no error you shared.
However, that error means that you’re using the Product schema and didn’t put/include any price or reviews:

Please note that the Product Schema is only for the actual product and not for anything else. You can check this link for more information:
https://developers.google.com/search/docs/data-types/product#guidelines
In this case, clear your website’s cache and revalidate the issue in your Google Search Console account and give Google some time to recrawl your site.

Looking forward to helping you.
You say there’s no problem, but I’m getting the error in the Google Console panel and my posts are being affected. I shared the screenshot below.
Hello,
Please click on the error to expand more details which should include the date of last crawl. Please share a screenshot of the expanded report.
Looking forward to hearing back from you.
