{"error":"1","msg":"id=0","found":0}

Hi,

I am trying to create a pipe, with
Pipe comes from here, RSS reader
http://www.hellodolly.be/?feed=rss

and
Pipe goes to herem Post.

The posts from the main blog should be replicated on the subsite with featured images.
When I try to test the pipe this error comes up:
{“error”:”1″,”msg”:”id=0″,”found”:0}

I can see it finds the posts etc, but the plugin stops here.
Any thoughts on how to resolve this ?
