New AWS Databricks connector broken in January (2026) release, Implementation = "2.0"

New Databricks connector in PowerBI (Implementation = “2.0”) is currently broken in the January (2026) release of PowerBI desktop. 
 
You have some choices: 

You can roll back to the November release of PowerBI desktop link is here: 
Previous monthly updates to Power BI Desktop and the Power BI service - Power BI | Microsoft Learn 

You can change your connections back to the default in PowerBI 
 
[Catalog="prod",  
        Database=null,  
        QueryTags=null,  
        EnableAutomaticProxyDiscovery=null,  
        Implementation=null] 

If you have large data and run into the Microsoft Hardy error message use the workaround with (EnableQueryResultDownload = "0") 
 
[Catalog="prod",  
        Database=null,  
        QueryTags=null,  
        EnableAutomaticProxyDiscovery=null,  
        EnableQueryResultDownload = "0",  
        Implementation=null] 

If your gateway is updated to the newest version, then you can continue to use the new connector you just need to use the November edition of PowerBI.  This is the ideal choice because we gain the performance of the new connector. 
 
If your PowerBI desktop is installed from the Company Portal then I recommend using the old default connectors until Microsoft gets their act together and fixes the connector in the next release. 
 
Some important implementation notes if you are using the old connector.  Only use EnableQueryResultDownload = "0" in your Power Query M Code if you get the Microsoft Hardy error message on your table.  Otherwise leave it off, so you get the performance gain. 
 
EnableQueryResultDownload = "0" forces a row-by-row refresh implementation as opposed to batches or chunks.  This is inefficient but reliable.

This issue is now resolved in the 2/20/2026 release of PowerBI desktop.  New connector is working as expected.
