Exception thrown while creating export_rocrate_json.cached

[pdurbin]

As of 2927c37 I did a mvn package (after disabling the failing test in #1) and copied files into place:

cp dataverse-rocrate-exporter-2.0.0-jar-with-dependencies.jar docker-dev-volumes/app/data/exporters
cp dataverse2ro-crate.csv docker-dev-volumes/app/data/exporters

Then, once Dataverse was up (using Docker):

pdurbin@beamish dataverse % docker exec -it -u 0 dataverse-1 bash
root@dataverse:/opt/payara# mkdir /exporters
root@dataverse:/opt/payara# cp /dv/exporters/dataverse2ro-crate.csv /exporters

Then I tried to export a dataset as RO-Crate: http://localhost:8080/api/datasets/export?exporter=rocrate_json&persistentId=doi%3A10.5072/FK2/75OJSF

This is the error I'm seeing:

On the Dataverse side I'm running the tip of the develop branch: IQSS/dataverse@ac32b00
