Error Message during sentiment analysis

Txter

Hi,

I'm performing a sentiment analysis of tweets using several excel spreadsheets (with Aylien operators), and this error message keeps popping up:

My workflow is as follows (it doesn't matter if I'm running just one of the workflow lines below, or all four — same error):

Any help/suggestions would be greatly appreciated. Thanks!

Hi,

i think the aylien extension is not able to run on collections of documents. Simply use the aylien operator taking example sets w/o the Data to documents should do it.
