I am trying to send a Trello card cover image / file attachment to Buffer. If I use card attachment the process works in test mode but when I publish it the Zap doesn’t run as ‘This Buffer step was safely halted’.
Zapier’s co-pilot suggests that I use Card Cover Scaled URL but when I do this the Zap run hits an error as the image is missing.
What should I be using to pass the URL of the image to Buffer?
