Alyien operator output problems

Hi everyone,

I'm trying to use Aylien Sentiment operator and everything seems fine (it works correctly) until I try to connect the output to another operator. I always get an error message:

aylien error.jpg

And the attribute list of the aggregate operator (in this case) is empty. Same problems with any operator that needs to read the example set from the Aylien operator.

Any ideas what might be wrong?

    Hi Jurij,


    Usually the metadata flows across the operators with no problems but not always. It appears that this is the case.  Double check to see if the Aggregate operator is even connected to the Aylien connector (i see a red input port, that means there's a connection problem).


    If the connection checks out another way to solve this problem is to just type in the name of the attribute (case sensitive) and toggle on "Syncronize Metadata with Real Data" in the Process pull down menu.
