data source ingest module

I installed the data source ingest module for python from “Autopsy: Python Tutorial #2: Writing a Data Source Ingest Module” and I edit this part, to display the data from the Account.db in artifacts. However, after I run the code on Autopsy nothing appears and there is no error. Any advice?

        # Open the DB using JDBC
        try:
            Class.forName("org.sqlite.JDBC").newInstance()
            db_conn = DriverManager.getConnection("jdbc:sqlite:%s" % lcl_db_path)
        except SQLException as e:
            self.log(Level.INFO, "Could not open database file (not SQLite) " + file_obj.getName() + " (" + e.getMessage() + ")")
            return IngestModule.ProcessResult.OK

        # Query the search table in the database and get specific columns.
        try:
            stmt = db_conn.createStatement()
            result_set = stmt.executeQuery("SELECT id,name,type,password FROM accounts")
        except SQLException as e:
            self.log(Level.INFO, "Error querying database for search table (" + e.getMessage() + ")")
            return IngestModule.ProcessResult.OK
        
        while result_set.next():
            try:
                
                _id = result_set.getString("id")
                name = result_set.getString("name")
                typr = result_set.getString("type")
                password = result_set.getString("password")

                self.log(Level.INFO, "Error getting values from contacts table (" + e.getMessage() + ")")
