google cloud platform – Wrong REST response for retrieving Column Level Lineage in GCP BigQuery

admin

I have got two BigQuery tables:
“bigquery:ssh-test-project-01.SSh_Dataset_03.SSh_BgQ_Src_01” and
“bigquery:ssh-test-project-01.SSh_Dataset_03.SSh_BgQ_Dst_BgQ_01”.

Using Data Transfer with SQL:
“SELECT Field_01,Field_02,Field_03 FROM ssh-test-project-01.SSh_Dataset_03.SSh_BgQ_Src_01“

I move all data into destination.

I see Table Level Lineage in Dataplex:

As well I see Column Level Lineage:

But if I try to get Column Level Lineage using REST request as described:
cloud.google.com/dataplex/docs/reference/data-lineage/rest/v1/projects.locations.processes.runs.lineageEvents/get

I have got response which seems wrong:

}

}

Is it a bug of Google implementation or I am doing something wrong ?
