Cloud DataFlow SQL from BigQuery UI cannot read Cloud Storage filesets: "Table not found: datacatalog.entry" - google-cloud-platform

Question

I'm trying to create a Data Flow job using the beta Cloud DataFlow SQL within Google Big Query UI.
My data source is a Cloud Storage Fileset (that is a set of files in Cloud Storage defined through a Data Catalog).
Following GCP documentation, I was able to define my fileset, assign it a schema and visualize it in the Resources tab of Big Query UI.
But then I cannot launch any Dataflow job in the Query Editor, because I get the following error message in the query validator: Table not found: datacatalog.entry.location.entry_group.fileset_name...
Is it an issue of some APIs not authorized?
Thanks for your help!

You may be using the wrong location in the full path. When your create a Data Catalog Fileset, check the location you provided, i.e: using the sales regions example from the docs:
gcloud data-catalog entries create us_state_salesregions \
--location=us-central1 \
--entry-group=dataflow_sql_dataset \
--type=FILESET \
--gcs-file-patterns=gs://us_state_salesregions_{my_project}/*.csv \
--schema-from-file=schema_file.json \
--description="US State Sales regions..."
When you are building your DataFlow SQL query:
SELECT tr.*, sr.sales_region
FROM pubsub.topic.`project-id`.transactions as tr
INNER JOIN
datacatalog.entry.`project-id`.`us-central1`.dataflow_sql_dataset.us_state_salesregions AS sr
ON tr.state = sr.state_code
Check the full path, it should look like the example above:
datacatalog.entry, then your location - in this example is us-central1, next your project-id, next your entry group id - in this example dataflow_sql_dataset, next your entry id - in this example us_state_salesregions
let me know if this works for you.
