error running rmlmapper-6.1.3-r367-all.jar

[xiaofengleo]

I am following the YARRRML tutorial (https://rml.io/yarrrml/tutorial/getting-started/), using the people.csv and episodes.csv as input.
I use the complete YARRRML files provided in this tutorial, quoted below:

prefixes:
  ex: http://www.example.com/
  e: http://myontology.com/
  dbo: http://dbpedia.org/ontology/
  grel: http://users.ugent.be/~bjdmeest/function/grel.ttl#

mappings:
  people:
    sources:
      - ['people.csv~csv']
    s: ex:$(id)
    graphs: 
      - ex:Characters
    po:
      - [a, schema:Person]
      - [schema:givenName, $(firstname)]
      - [schema:lastName, $(lastname)]
      - p: e:debutEpisode
        o:
         value: $(debut episode)
         datatype: xsd:integer
        graphs: 
          - ex:Episodes
      - p: dbo:hairColor
        o:
          function: grel:toUpperCase
          parameters:
            - [grel:valueParameter, $(hair color)]
          language: en
      - p: e:appearsIn
        o:
          mapping: episode
          condition:
            function: equal
            parameters:
              - [str1, $(debut episode), s]
              - [str2, $(number), o]
        g: ex:Episodes
  episode:
    sources:
      - ['episodes.csv~csv']
    s: ex:episode_$(number)
    po:
      - [a, schema:Episode]
      - [schema:title, $(title)]

Then I run yarrrml-parser -i .\idf.yml -o idf.rml.ttl
The idf.rml.tll file looks like below:

Then I run java -jar ./rmlmapper-6.1.3-r367-all.jar -m .\idf.rml.ttl
and get following error:

Exception in thread "main" java.lang.Error: No Triples Maps found. The mapping document you should at least have one Triples Map.

my yarrrml-parser version is 1.4.0
my rmlmapper is 6.1.3-r367-all, as its name indicates.

I found a similar issure at RMLio/rmlmapper-java#13, but still not able to fix the error I have.

Any help is appreciated.

By changing the RML prefix at prefix.cc, we had a small bug in the YARRRML-parser. We pushed v1.5.0 today, could you update the yarrrml-parser and try again?

Yes, it works for me. Thank you very much.
