Region mismatch error with wrangler in Amazon SageMaker

Hi everyone,

I am facing an issue while creating Amazon Redshift wrangler in Amazon SageMaker Studio. I receive the following error message: A customer error has occurred. See the error reason below. RedshiftConnectionValidationError: Unable to validate connection. An error occurred when trying to list schema from Redshift: An error occurred (ValidationException) when calling the ListSchemas operation: Redshift endpoint doesn't exist in this region.

However, both my Redshift Serverless cluster and SageMaker instance are definitely in the same AWS region. I followed the steps in this AWS guide to set up the connection but still no luck.

Has anyone encountered this issue before or have any suggestions on how to resolve it? I have already double-checked the region settings for both services, and everything seems to be configured correctly (such as role, security group inbound).

Any guidance or troubleshooting steps would be greatly appreciated.

Regards
