The text length cannot exceed the limit 50

Question

I'm trying to import a Watson conversation app to a LUIS app, I have already converted the json to its equivalent in LUIS converting all Watson entities into Lists with synonyms, but when I try to import it to LUIS I get the following error:

The text length cannot exceed the limit 50

What's the cause of this and how can I fix it? It may be related to the limit of 50 explicit lists detailed here, if that's the case what exactly is a explicit list? I couldn't find any documentation related.

Answer 1

The entity name or the list normalized value or the list value synonym is more than 50 char.
