Help please - How to get slack to pickup meta image

Hello, 

I need my meta image to be a dynamic link as it will change daily. I've got this working on AWS lambda, but when I use code inject and update the og:image, slack doesn't pick it up and will not post the image to slack at all. 

I have even tried hardcoding an image link and slack will not pick it up. 

Example of my hardcoded meta image data:

<meta property="og:image" content="https://imgur.com/FxF31ba" />

and the logs from slacks unfurl debugger:

Request to fetch https://cyan-aardvark-7kb7.squarespace.com/boards/index returned HTTP 206
Type of resource is text or HTML
Found data in meta tags

This is a webpage not an image. If you want to pull from that location, then try this link:

<meta property="og:image" content="https://i.imgur.com/FxF31ba.png" />

Darn, I hoped I had spotted a simple solution! This is generally muddy as a problem and linked heavily to cache so can be really difficult to get an image to pull through correctly and even worse to try and replace. I don't believe that Slack has a tool for scraping posts, but LinkedIn does:

Ah yeah it works perfect on the LinkedIn post inspector. What a shame!! 
Thank you
