Issue
When downloading a view image using the Tableau Server Client views.populate_image method, the view cache is not refreshed and an outdated view is returned.
Last Modified Date: 15 Feb 2019
Environment
- Tableau Online
- REST API
- Tableau Server Client (Python)
Resolution
Use the maxAge URL parameter (?maxAge=<# of minutes>) to set the max age value of a view's image cache. This feature is available for REST API/Tableau Server Client in version 2019.1 and later.Cause
The 'Query View Image' API endpoint is expected to pull from cache based on the vizportal.rest_api.view_image.max_age setting.Thank you for providing your feedback on the effectiveness of the article.
