inspectIT/Ocelot

Hi @JonasKunz , I tried to implemet JDBC tracing for MSSQL prepared statement by referring the HSQL db conf in demo app.
getting below exception. Database name gettting printed in trace but not SQL queries.
below is my instrumentation config

inspectit:
  instrumentation:
    data:
      db_name: {down-propagation: NONE, is-tag: false}
      sql: {down-propagation: NONE, is-tag: false}
      servicegraph_is_entry: {down-propagation: NONE, is-tag: false}
    scopes:
      mssqldb_prepared_statement_execute:
        type:
          name: com.microsoft.sqlserver.jdbc.SQLServerPreparedStatement
        methods:
          - name: execute
            matcher-mode: STARTS_WITH
    rules:
      mssql_get_prep_statement_sql:
        scopes:
          mssqldb_prepared_statement_execute: true
        tracing:
          attributes:
            database: db_name
            sql: sql
        entry:
          db_name:
            action: get_jdbc_statement_connection_name
          sql:
            action: mssql_prepared_statement_get_sql
     actions:
        mssql_prepared_statement_get_sql:
        imports:
          - com.microsoft.sqlserver.jdbc
          - java.lang.reflect
        input:
          _this: SQLServerPreparedStatement
          _class: Class
        value-body: |
          Field sqlField = _class.getDeclaredField("sql");
          sqlField.setAccessible(true);
          return sqlField.get(_this);

      get_jdbc_statement_connection_name:
        imports:
          - java.sql
        input:
          _this: Statement
        value-body: |
          if(!_this.isClosed()) {
            Connection con = _this.getConnection();
            String url = con.getMetaData().getURL();

            int semiColonIndex = url.indexOf(';');
            if(semiColonIndex != -1) {
              url = url.substring(0,semiColonIndex);
            }

            int questionIndex = url.indexOf('?');
            if(questionIndex != -1) {
              url = url.substring(0,questionIndex);

When I execute with this configuration only DB name is getting logged in trace.
Encountering below exception.
