I created a new workspace on Azure Databricks, and I can't get past this first step in the tutorial:

DROP TABLE IF EXISTS diamonds;

CREATE TABLE diamonds USING CSV OPTIONS (path "/databricks-datasets/Rdatasets/data-001/csv/ggplot2/diamonds.csv", header "true")

error:

UnityCatalogServiceException: [RequestId=1a282f93-a134-4639-ac88-65798d67c924 ErrorClass=INVALID_PARAMETER_VALUE] GenerateTemporaryPathCredential uri /databricks-datasets/Rdatasets/data-001/csv/ggplot2/diamonds.csv is not a valid URI. Error message: INVALID_PARAMETER_VALUE: Missing cloud file system scheme.

adding dbfs: didn't fix my issue, as suggested here. instead I got:

AnalysisException: [UC_FILE_SCHEME_FOR_TABLE_CREATION_NOT_SUPPORTED] Creating table in Unity Catalog with file scheme dbfs is not supported. Instead, please create a federated data source connection using the CREATE CONNECTION command for the same table provider, then create a catalog based on the connection with a CREATE FOREIGN CATALOG command to reference the tables therein.

I also browsed the file system (with ls commands) and saw the file there.

Note: I got this working properly on AWS Databricks
