Accessing concatenated information not working

Hello community

I'm trying to display  the content of two attributes as a single entry in a glossary. The steps I've followed are as follows:

1. Added   a new field called idynombre as procedure in the corresponding transformation item as attributeConcat of identifier + name

   

2. Added the new field in glossary factsheet:

   

   But when I try to see  the glossary nothing is displayed:

   

   And in copernicus.publishing.log file I can see these messages:

   Am I missing any additional steps?

    

   Thanks in advanced
