Troubleshooting

The following table contains the most common issues that you can encounter while ingesting or synchronizing Tableau.

Issue	Solution
Tableau images are not fetched correctly	Synchronizing Tableau data means ingesting metadata from Tableau to your Collibra Data Intelligence Cloud environment. The metadata is represented as assets of specific types and their characteristics. Images such as report thumbnails are not downloaded and stored in Data Catalog. Instead, Data Catalog stores a link to the image. Every time you open the asset page, the image is fetched from Tableau. Images are not fetched correctly if there is a problem with this link. A common issue is caused by the base URL parameter, which is part of the link. If the base URL is not set correctly in Collibra Console, the links to the Tableau images are broken. To fix this issue, edit the base URL in Collibra Console.
When you synchronize a Tableau Server 2020.2, some Tableau data is skipped.	In most cases, this occurs when people are actively using Tableau while Data Catalog is synchronizing the Tableau Server. The technical reason is that the APIs collect Tableau data at different times. If users make changes in Tableau, the data that is collected by the APIs may be inconsistent. When that happens, the corresponding assets are not synchronized in Data Catalog. We highly recommend that you synchronize Tableau after working hours. This reduces the chance that Tableau data is added, changed, renamed or deleted on Tableau's side during the synchronization process.
Tableau synchronization fails with error message `Duplicate key`.	The Tableau synchronization fails with the `Duplicate key` error when you have multiple views with the same name in the same workbook. To solve this problem, we highly recommend to give each view in Tableau a unique name before you synchronize the Tableau Server in Data Catalog.

Solution

Tableau images are not fetched correctly

Synchronizing Tableau data means ingesting metadata from Tableau to your Collibra Data Intelligence Cloud environment. The metadata is represented as assets of specific types and their characteristics. Images such as report thumbnails are not downloaded and stored in Data Catalog. Instead, Data Catalog stores a link to the image. Every time you open the asset page, the image is fetched from Tableau.

Images are not fetched correctly if there is a problem with this link. A common issue is caused by the base URL parameter, which is part of the link. If the base URL is not set correctly in Collibra Console, the links to the Tableau images are broken.

To fix this issue, edit the base URL in Collibra Console.

The Tableau synchronization fails with the Duplicate key error when you have multiple views with the same name in the same workbook.

To solve this problem, we highly recommend to give each view in Tableau a unique name before you synchronize the Tableau Server in Data Catalog.
