Error connecting Report Builder to Azure Databricks

[fbottazzoli]

Since yesterday, I'm facing issues with connecting to Azure Databricks from Report Builder. 

For connecting, I'm using function: 

Databricks.Query(Azure_Databricks_Instance, Azure_Databricks_Compute , [Catalog=null, Database=null, EnableAutomaticProxyDiscovery=null])

with all parameters set correctly and never changed since weeks.

Suddenly, the following error began to occurr: 

Do you have any idea what could be the reason for this error?

Thank you in advance for any help.

Hi @fbottazzoli ,

The error message indicates a problem with the parameter.

Here are some of my suggestions:

• Make sure that all parameters in the Databricks.Query function are set correctly. If any of them are set to null, try providing explicit values.
• DefaultTypeParameter indicates that the default value of the parameter is not recognized. Check if the parameter has been changed recently.
• Since the error message is in Italian, make sure that the system's language or locale settings match the expected configuration for Azure Databricks.

If these steps do not resolve the issue, can you share more details about your recent changes? This will help resolve your issue.

Hello Yang,

no recent change was made and all the parameters were correctly set . After further investigation, we finally succeeded in solving the issue by replacing Databricks.Query function (that suddenly stopped working on paginated reports / report builder, but luckily not in Power BI) with Value.NativeQuery function.

Do you know if something changed in the integration of Databricks.Query in Report Builder recently?

Thank  you

Hi @fbottazzoli ,

Based on the latest updates and release notes for Azure Databricks and related integrations, there doesn't appear to be any explicit documentation about the function changes in Report Builder. I would recommend keeping a close eye on the URL below to see if there are any announcements or fixes:
