PowerAutomate SQL Server Connector could execute stored procedure for on-premises data gateway but no data was updated.

Hi, we have developed a PowerApp with PowerAutomate flow that connects to an SQL Server via On-premises data gateway. During tests, we have separately executed a Stored Procedure on the database side with no issue, when we connected the stored proc to our PowerAutomate flow and ran some tests, we didn't encounter any error (also checked the passed stored proc parameter) but on database-end, there's no updated data (though table insertion works). Why is this happening?
