I think we need to update the paths, the read APi will be available under /technical_lineage_resource/rest/lineageGraphRead/v1 , /technical_lineage_resource is to target the lineage proxy on dgc (the one injecting the required lineage token) and /rest/lineageGraphRead/v1 is the APIprefix from https://github.com/collibra/lin-graph/blob/main/lin-graph-api/src/main/resources/oas/LineageRead.yaml
