Image format? Asana to Buffer Integration with Zapier

I am trying to use load an attached image in an asana task directly to buffer. What shows up in the zap is a LOOOONG url and then the zap tells me the format is incorrect. My options include an Attachment ID, Attachment Name, and then the URL Attachment. I have tried formatter to extract something usable and am having no luck.

HELP?!

Hi Did you manage to get this sorted?

I want to know this aswell.

Have the same problem here… anyone found a workaround ?
