TypeError: Cannot read properties of undefined (reading '0') using client.openSession();

Inizia riproducendo il malfunzionamento di app/api/databricks-test/route.ts con l'alias webpack in next.config.js, quindi confrontalo con examples/usage.js. Segui il percorso di openSession attraverso @databricks/sql e node-int64/Int64.js e verifica che il workaround lz4 non causi più il TypeError. Il lavoro è completato quando la sessione si apre, la query di esempio restituisce un risultato e ogni ramo del route-handler restituisce una risposta.

Previously working code causing a TypeError: Cannot read properties of undefined (reading '0'). This code is from the following example: https://github.com/databricks/databricks-sql-nodejs/blob/HEAD/examples/usage.js

const { DBSQLClient } = require('@databricks/sql');
import { DBSQLLogger, LogLevel } from '@databricks/sql';
import { NextResponse } from "next/server";



export async function POST(){

const logger = new DBSQLLogger({ filepath: 'log.txt', level: LogLevel.debug });
    
    
const client = new DBSQLClient({ logger: logger });
console.log("CREATED CLIENT");

client
  .connect({
    host: process.env.DATABRICKS_SERVER_HOSTNAME,
    path: process.env.DATABRICKS_HTTP_PATH,
    token: process.env.DATABRICKS_TOKEN,
  })
  .then(async (client: { openSession: () => any; close: () => any; }) => {
    const session = await client.openSession();
    console.log("SESSION CREATED");

    const queryOperation = await session.executeStatement('SELECT "Hello, World!"');
    const result = await queryOperation.fetchAll();
    await queryOperation.close();

    console.table(result);

    await session.close();
    await client.close();
    return NextResponse.json(result);
  })
  .catch((error: any) => {
    console.log(error);
    if (error instanceof Error) {  
        console.error("Error executing query: ", error);  
        return NextResponse.json(  
          { error: "Failed to execute query: ", details: error.message },  
          { status: 500 }  
        );  
      }  
  });
}

Console output:

{"level":"info","message":"Created DBSQLClient"}

The only change made was adding:

webpack: (config) => {
       config.resolve.alias.lz4 = false;
    
       return config;
     },

to my next.config.js to prevent the following error:

Module not found: Can't resolve '../build/Release/xxhash'```
