Redshift datashare same account requires encryption

Hello , I created datashare between serverless redshift workgroup and a provisioned redshift cluster ,

`

-- serverless

CREATE DATASHARE aggregated_tables
SET PUBLICACCESSIBLE = TRUE  ;


ALTER DATASHARE aggregated_tables
ADD SCHEMA public ;

ALTER DATASHARE aggregated_tables
ADD SCHEMA audience_insights ; 

ALTER DATASHARE aggregated_tables
ADD ALL TABLES IN SCHEMA public, another_schema ;

ALTER DATASHARE aggregated_tables
SET INCLUDENEW = TRUE FOR SCHEMA public; 

ALTER DATASHARE aggregated_tables
SET INCLUDENEW = TRUE FOR SCHEMA another_schema; 

GRANT USAGE ON DATASHARE aggregated_tables
TO NAMESPACE 'provisioned_namespace' ;
-- provisioned namespace

DESC DATASHARE aggregated_tables ; 

`

And on provisioned I ran : `

-- Permanent redshift

CREATE DATABASE shared_aggregated_database
FROM DATASHARE aggregated_tables
OF ACCOUNT 'XXXXXX' namespace 'serverless_namespace';
-- serverless namespace

DESC DATASHARE aggregated_tables OF ACCOUNT 'xxxxxxx' NAMESPACE 'serverless_namespace';`

In the editor the shared_aggregated_database is empty

and when i ran a query directly i receive ERROR: The consumer and producer cluster have different encryption type.

Serverless is encrypted by default , provisioned cluster is NOT , they are both on same aws account .

In documentations it only mentions encryption for CROSS ACCOUNT ACCESSS

https://docs.aws.amazon.com/redshift/latest/dg/considerations.html

or is it also required for same account ??
