The issue seems to be the missing backticks around the principal name:

status = StatementStatus(error=ServiceError(error_code=<ServiceErrorCode.BAD_REQUEST: 'BAD_REQUEST'>, message='\nOperation not ...ne 1, pos 0)\n\n== SQL ==\nGRANT USAGE ON SCHEMA default TO sdk-p6ja\n^^^\n'), state=<StatementState.FAILED: 'FAILED'>)
