Oracle Analytics Cloud – Data Modeler Connection Issue (ADF_FACES-60097)

I login to the Oracle Analytics Cloud (OAC), and I successfully created a database connection to the Autonomous Data Warehouse database on the same tenancy (Clicked on the “Create” button then Connection”:

Then I selected the connection type as “Oracle Autonomous Data Warehouse”:

Then I entered the connection Details:

Connection was created successfully, and I can now browse the schema objects and view data and create reports.

After that I launched the Data Modeler, as follows:

Then I selected “Launch Data Modeler”:

But interestingly, the Connections list of values item has no connections, and I I clicked “Refresh Connections, I got the following two errors:
ADF_FACES-60097 & ADF_FACES-60096

Also, If I tried to create a new model, the database field has no data source, as appears in the following screen:

So, it looks like the connections that I created from the OAC home page are local to OAC and not visible in the Data Modeler.

So, I decided to create a new connection from the OAC Console as Follows:

This connection is visible now from the Data Modeler, and I can successfully create a new data model:

Please note that the connections created from OAC Console are visible from the Data Modeler, not from the OAC itself.

Hope this is helpful
