v1 Initial RDF migration breaks if persistentUrl contains ipv4

[dennisvang]

description

Using a v1 fdp with GraphDB.

If the persistentUrl config value contains an ipv4 address instead of a fully qualified domain name (fqdn), the initial RDF migration fails with the following error:

ERROR nl.dtls.fairdatapoint.database.rdf.migration.production.Rdf_Migration_0001_Init -
   Transaction handling error: Invalid IRI value

and the fdp service fails to start.

how to reproduce

1. clone the FAIRDataTeam/compose repo
2. cd compose/fdp/persistent/v1
3. temporarily edit the compose.override.yml file to include the following in the fdp.environment:
   INSTANCE_PERSISTENTURL: http://127.0.0.1
4. docker compose up -d
5. wait and observe that the fdp fails to start
6. check logs: docker compose logs fdp
7. [optional] clean up: docker compose down --volumes

You can also verify that it does work if we specify INSTANCE_PERSISTENTURL: http://localhost (this is actually the default used by persistent/v1, as can be seen in compose/fdp/components/v1/fdp.yml).

workaround

For now, just use a fully qualified domain name instead of an ipv4 address...

notes

• Does not occur with the ephemeral/v1, which uses an in-memory triple store, so it is probably related to graphdb
• Haven't tried to reproduce this in v2 yet...

• check if this still occurs with Bootstrap (RDF) triple store from fixtures #785
