Error: invalid because the given value '' for property 'og:image:url' could not

Hi ,

OUr website https://powdercoatingireland.com/ is not working when we are hitting the like button on homepage. But on other pages/post are fine.

I tried the https://developers.facebook.com/tools/debug and put our domain and it says … “Object at URL ‘https://powdercoatingireland.com/’ of type ‘blog’ is invalid because the given value ” for property ‘og:image:url’ could not be parsed as type ‘url‘.” but i honestly don’t understand how to fix.

I tried to work on some of the answer i found on same issue as mine but not working.

PLease help ^^

Thanks and Happy New Year…
