IFTTT integration with trello File Not Found

[Vic]

Hi,  I have the IFTTT integration working great with Trello, but when it triggers and creates the card in trello, there is a big picture with the words "File not found" in it.  I did a little searching and found something that said to use a recipe that does not use an attachment but I can't see how to remove that field from the recipe.

The applet looks for a card added to a specific list on a specific board that is assigned to me.  When that happens, it then makes a copy of that card and puts it into another list on another board.  

In the recipe, one of the ingredients that is default is "Attachment URL (optional)".  I've tried both leaving that field blank, or using something like "{{CardURL}}".  The new card is created in the right place but there is a cover on the card with the file not found image.  How do I get that to stop???

Thanks!
