Troubleshooting steps attempted [note that we will not prioritise posts unless there is evidence of following the troubleshooting guides]: Card validator says Unable to render Card preview INFO: Page fetched successfully WARN: No metatags found
But as you can see in the preview of this topic I can see card is rendered. And also when i share this link Card is not shown
I got the issue. HTTP header was returning content-type as application/json where it should have been text/html
