Hi @mertozsoy
The link to the image doesn’t seem to be loading as expected. Could you possibly upload a screenshot to imgur.com or snipboard.io and send us a link to the image so we can check on this further?
Please also do provide us with an example URL where you are getting this ‘mainentity’ field is missing error. We do know this happens when you set a page as a FAQPage in the Yoast SEO schema settings but don’t use the Yoast FAQ block, as it would lack the proper and valid markup.
You can learn more about it here – https://yoast.com/help/selecting-content-types-in-schema-settings/
Hi @mertozsoy
Thanks for providing that information.
It looks like for this URL https://teknikmi.com/lenovo-p2-ekran-degisimi-orijnal-lcd-ekran/, you’ve set it as a FAQPage, but are indeed not using the Yoast FAQ block (which is needed to add the appropriate markup).
In order to resolve this, you can either set the schema setting back to ‘WebPage’ or add the Yoast FAQ block – https://yoast.com/features/structured-data-blocks/
If you add the Yoast FAQ block, we would expect that it would add the correct and missing ‘mainEntity’ markup, and you would then be able to validate the fix in Google Search Console after.
We are going ahead and marking this issue as resolved due to inactivity. If you require any further assistance please create a new issue.
