Data Quality Error (Internal Service Error)
I am facing an issue while running the DQ scan, when i tried doing manual scan and scheduled scans both time i faced Internal Service Error.
( DataQualityInternalError Internal service error occurred .Please retry or contact Microsoft support )
Data Profiling is running successfully but for none of the asset, DQ is working.
After the lineage patch which MS had fixed, they had introduced Custom SQL option to create a rule, and after that only i am facing this issue.
Is anyone else also facing the same? I tried with different data sources (ADLS, and Synapse) its same for both.
If anyone has an idea, do share it here, it will be helpful.

Hello tatatayryryr,
Many reasons why this error could occur. Please refer to: https://learn.microsoft.com/en-us/purview/unified-catalog-data-quality-troubleshooting#my-data-quality-scan-job-failed-i-see-an-error-message-internal-service-error-occurred-please-retry-or-contact-microsoft-support-what-should-i-do-to-troubleshoot
If related to authentication, the supported authentication mechanism to run data quality scans is using Managed Identity as described in the documentation here - https://learn.microsoft.com/en-us/purview/how-to-configure-and-run-data-quality-scan#supported-authentication-methods
If none of this help, try the following,
- Delete the data product
- Re-create the data product with the data asset.
- Publish the data product.
- Run data quality scan
Hope this helps!
