Suggestions on how to test this:

1. Load a metadata block TSV that defines a field with type "string"

   example: https://gist.github.com/vera/fc39e7b0bb0e9da7dc24a41c680f6d59

   curl http://localhost:8080/api/admin/datasetfield/load -H "Content-type: text/tab-separated-values" -X POST --upload-file stringtest.tsv

2. Activate metadata block

   curl curl -H "X-Dataverse-key:$API_TOKEN" -X POST -H "Content-type:application/json" -d "[\"citation\", \"stringTest\"]" http://localhost:8080/api/dataverses/:root/metadatablocks

3. Update Solr schema

   curl "http://localhost:8080/api/admin/index/solr/schema" | ./update-fields.sh schema.xml

   docker cp schema.xml solr-1:/var/solr/data/collection1/conf/schema.xml

   curl "http://localhost:8983/solr/admin/cores?action=RELOAD&core=collection1"

4. Confirm that the updated Solr schema contains a new field with type "string"

    <field name="testStringField" type="string" multiValued="false" stored="true" indexed="true"/>
   ...
    <copyField source="testStringField" dest="_text_" maxChars="3000"/>
   

5. Create a new dataset via the UI (or API)

   

6. Verify the string value correctly ends up in Solr and can be seen on the dataset page

Could you please update this PR with the latest from Develop? Need pom.xml to show 6.6. Thanks!

@vera or @johannes-darms will have to do it. I tried but I don't have permission. 😅

Done!

Apparently, the option "Allow edits by maintainers" isn't available for PRs made from forks owned by organizations, so that's why you couldn't push @pdurbin ... Too bad (but a request to change that is open here: https://github.com/orgs/community/discussions/5634)
