FAQ

Name of Tableau dashboards in the catalog show as null, or some elements in the Tableau lineage show as null:null

The current Personal Access Token in use is associated to a user not having the right permissions to see all levels of information on your Tableau site.

When using the Tableau Metadata API, Sifflet will collect all metadata informations related to assets on your Tableau instance. However, due to permission settings, the Personal Access Token (and by extension the user) might not be allowed to access all assets and details about those assets. In the Tableau user interface this translate by not having access at all to those assets, but with the Metadata API this translates by retrieving obfuscated information marked with null leading to partial information available on Sifflet.

This can lead to Sifflet not being able to create a full lineage between your tables/views and your Tableau database/dashboards.

How to solve this issue?

Please ensure to generate a Personal Access Token from a user with at least "Site Administrator Explorer" role.

Once you have changed the user role or updated to a new Personal Access Token (see section 3), refresh the Tableau integration (Integrations -> Sources -> filter to Tableau -> Run Source).

For more information about Tableau roles and how to change a user's role, see this documentation.
