We have a share button (our own button) for our clients. For a page such as:
https://www.wyomingforsale.net/idx/listing/WY-CCBOR/22-658/3-Pine-Cone-Ln-Moorcroft-WY-82721
We get to this page:
https://www.facebook.com/sharer/sharer.php?u=https%3A%2F%2Fwww.wyomingforsale.net%2Fidx%2Flisting%2FWY-CCBOR%2F22-658%2F3-Pine-Cone-Ln-Moorcroft-WY-82721&
The problem is that the image is blank. There is a valid og:image tag on the page. I have used the sharing debugger with the same results - the preview shows an empty image. The canonical URL looks correct and identical to the fetched URL. Looking in the debugger at the value for og:image, that URL looks good, and if I plug that into my browser, the image shows up. What am I missing? This is a React-drawn page, if that makes any difference.
