Problem with SAP SQL debugger

Hi,

I am using the Web IDE workbench

I have a problem when trying to execute the following code in the SQL code:

call HCP.HCP_GRANT_ROLE_TO_USER('{{PACKAGE_NAME}}::helloworld_user','{{USER_NAME}}')

I get this error

12:39:59 PM (SQL Debugger) Error in Main WebSocket Connection to backend for SQL debugging...

12:39:59 PM (SQL Debugger) The Main WebSocket Connection for SQL debugging was closed...

12:39:59 PM (Content Persistence) Could not restore tab since editor was not restorable.
