Are these hosted on Tableau Server and being refreshed from there? A issue was found and resolved in later releases: https://kb.tableau.com/articles/issue/json-data-source-not-refreshing-using-live-connection-on-tableau-server
If the issue is the connector is picking up all the schemes as expected the file can be forced to complete a full scan. More information can be found here: JSON File
The connections to Blob data from Tableau Desktop is a feature request for the product. Please upvote the idea linked below.
Hope this helps!
In a similar vein to the KB article, I have a JSON problem. I have Tableau Server 2018.1.2 so it should be internally resolved according to that article.
I have a JSON data source that has a live connection to Tableau Server. The JS data source is updated via script on a daily basis and began doing this about two weeks ago.
In Tableau Desktop, the date variable was originally coming through as a string as JS has no real inherent data type for dates. I changed it to Date within Tableau Desktop but was not sure if that format would hold as the new data got uploaded daily. Even though the data source is seemingly being updated daily with new data, when I look at the data the maximum date available is the maximum date that was available when I last changed the format of the Date variable from string to date.
Is it not recognizing the new data because it is coming through as a string?
Thanks for any and all insights!
