DPONE_PIPELINE_ID_DUPLICATE¶
Audience: pipeline authors and repository maintainers.
The same pipeline id exists in more than one project location. Pipeline ids are project-wide identities in domain-first v1, so a duplicate would make selection, evidence, and Airflow DAG ownership ambiguous.
Detect every conflicting authority:
Choose a project-unique id and rerun the original scaffold with the same route arguments:
dpone init pipeline <new-id> \
--domain <domain> \
--route <source>:<sink>:<strategy> \
--from <source-ref> \
--to <sink-ref> \
--key <column>
dpone check <domain>/<new-id>
There is no automatic rename because references and evidence may depend on the old identity. No files are created by the failed attempt. Escalate to a reviewed authoring migration when the existing id must be retained.
