Unity Catalog Internal Error - UC_INTERNAL_ERROR (#UC-AUDKE) while accessing Sample Data in Catalog Explorer

Question

Hi Team,

I am currently facing an issue in Azure Databricks while accessing table data through Unity Catalog.

I have successfully created the catalog, schema, and table, and I am able to view the table in Catalog Explorer. However, when I navigate to the Sample Data tab to preview the records, I receive the following error:

"Error getting sample data

Your request failed with status FAILED: [BAD_REQUEST]

ErrorClass=INTERNAL_ERROR.UC_INTERNAL_ERROR

You have encountered an internal error.

Please contact Databricks support with the error code #UC-AUDKE".

I have already verified the following:

• Table is visible in Catalog Explorer.
• Required permissions have been granted.
• Browser refresh and retry did not resolve the issue.
• The issue occurs consistently whenever I try to access the Sample Data tab.

Could you please help investigate the root cause of this error and advise on any additional troubleshooting steps? If this requires backend investigation, kindly let me know.

Thank you for your support.

Hi @RAJLAXMI

Root Cause :

Please confirm are you using free account and using the compute are serverless. if your using serverless you not able to fetch data from Catalog Explorer directly.

Solution :

if you want use serverless compute execute queries from your notebook. it will be execute.

SELECT * FROM catalog.schema.table LIMIT 10;

if you want to use catalog explorer you need to configure or add new compute based on your minimum requirements.

Thanks.
