Macro Error: Optional Anchor is Empty?

[cgarcia0622]

I'm lost as to why my workflow is giving an error. It states " The incoming dataset on the optional workflow is empty." But, as you can see in the screenshot there is data coming in.

Hi @cgarcia0622 

What about the connection to the control input?  Does it have data?

I'm assuming that's the upside down question mark but yes it has a list of file paths
