Need to join the input array of objects to string

@Bhavin, I think what Mike is saying is that the File Reader has a binary input which requires a binary formatter of some sort which does not pass through the document variables that would otherwise be available to the File Reader if it had a JSON input.

@mikeandrews, I’ve run into the same issue and the only way I’ve been able to get this to work in the past is with two pipelines. The first ending with a Pipeline Execute or For Each snap which would assign the filename variable value to a parameter provided by the second pipeline which contained the File Reader snap.

For the same or similar use case, a couple of years ago, I had suggested to a SnapLogic representatives the need to make pipeline parameters variable rather than static. I even suggested a new variable array could be added as a property to the pipe object. However, this was an in-person, casual conversation and may not have made it to the request queue.
