Datatype for constant value triggers error (yatter v1.1.2)

[TijnDeWever]

Describe the bug Version 1.1.2 of yatter can't translate the following code (version 1.1.0 had no problem with it):

prefixes:
 ex: "http://www.semanticweb.org/tijnd/"
 schema: "https://schema.org/"
 rdf: "http://www.w3.org/1999/02/22-rdf-syntax-ns#"
 rdfs: "http://www.w3.org/2000/01/rdf-schema#"
 xsd: "http://www.w3.org/2001/XMLSchema#"

sources:
  imdb:
   access: imdb_video_game_rating_modified.csv
   referenceFormulation: csv

mappings:
  Rating:
    sources:
      - imdb
    s: ex:$(title)
    po:
      - [a, schema:Rating]
      - [schema:author, ImDB, rdfs:Literal] 

Error:

When the datatype is removed (like this - [schema:author, ImDB]) the code can be translated successfully by yatter (v.1.1.2). The same YARRRML document (including the datatype) can be translated with Matey.

I'll look into it! Thanks for the issue :-)

I think it's solved, we are having some problems with the publication in PyPI so if you want to use it, you'll need to install the engine from the source code.

cd src
python3 setup.py install

Yes, it works. Thanks (for the quick response)!
