Following BQ Clustering recommendations does not work - UPDATE SET CLUSTER_FIELD does not exist

[rchrand]

Following the https://cloud.google.com/bigquery/docs/apply-partition-cluster-recommendations#apply_cluster_recomme... documentation leads to the 2nd step where you'll need to run this SQL command:

`UPDATE DATASET.TABLE SET CLUSTER_COLUMN=CLUSTER_FIELD WHERE true`

Where it returns with error that the cluster_field doesn't exist.
