`DATAIO_NULL` string in CSV mapping output using 7.0.0

[namedgraph]

With the previous version the output was:

<https://data.beamery.com/smth/9#this> <http://www.w3.org/2004/02/skos/core#definition> "VP STRATEGIC ACCOUNTS, NA\n\nBeamery \n
***truncated***"@en .

With version 7.0.0 the output is:

<https://data.beamery.com/smth/9#this> <http://www.w3.org/2004/02/skos/core#definition> "VP STRATEGIC ACCOUNTS, NA\nDATAIO_NULL\nBeamery \n
***truncated***"@en .

CSV row looks like this (multiline string value):

9,"Vice President, N/A Strategic Accounts",9,"VP STRATEGIC ACCOUNTS, NA

Beamery 
***truncated***"

YARRML mapping:

  Concept:
    sources: smth
    s: smth:$(id)#this
    po:
      ...
      - [ skos:definition, $(role_description), en~lang ]

Hi!

Can you please add a reproducible example for this issue?
We're trying to solve this, but the mapping's source access description is missing and the CSV header as well.
Would it be possible to make a toy example that reproduces the problem? Thanks!

Attaching the files (zipped): rmlmapper_test.zip

The command (ran within the rmlmapper_test folder):

docker run --rm \
  -v "$PWD":"/data" \
  rmlio/rmlmapper-java:7.0.0 \
  -m /data/mapping.ttl \
  -o /data/output.nt \
  -s ntriples \
  -d

I have the same issue with any CSV that has multi-line values containing empty lines (e.g. \n\n). Perhaps related to the 1.1.0 release of the dataio library and the NewCSVNullInjector that was introduced?

@DylanVanAssche any updates on this?

[DylanVanAssche]

@namedgraph This is fixed in dataio: RMLio/dataio@6ba79ab available in dataio 1.3.1.

A new release of RMLMapper needs to be made with dataio updated to 1.3.1

[DylanVanAssche]

Fixed in v7.1.0
