Error "Basic authentication or X-Trino-User must be sent" When Connecting to Trino from Tableau Cloud

Publiceringsdatum: Apr 30, 2025
Beskrivning

When connecting to Trino (formerly known as PrestoSQL), the following error may occur:

Bad Connection: Tableau could not connect to the data source.
Error Code: FAB9A2C5
Authentication failed: Basic authentication or X-Trino-User must be sent
Unable to connect to the Presto server "<server name>". Check that the server is running and that you have access privileges to the requested database.

Cause

Tableau Cloud currently uses the Simba Presto ODBC Driver (64-bit) version 1.1 with the Presto connector. This driver expects the HTTP client protocol headers to start with X-Presto-.
Lösning
Configure the Trino server to support connections using the Simba Presto ODBC Driver (64-bit) version 1.1 by adding a configuration property: 
protocol.v1.alternate-header-name=Presto

For more information about the protocol.v1.alternate-header-name configuration property, see this Trino document.
