Data not being added to Redis during integration test

Question

I am attempting to write a integration test for my expressjs router with a Redis store.

const request = require('supertest'); 
const redisClient = require('../../startup/redis-client');

describe('/api/', () => {
    beforeEach(() => {
        server = require('../../index');
    });

    afterEach(async () => {
        await redisClient.flushAll();
        await redisClient.disconnect();
        server.close();
    });

    describe('GET /:key',  () => {
        it('should return the key', async () => {
            console.log(redisClient);

            await redisClient.set('key1', 'value1');

            
            await redisClient.set('key2', 'value2');

            const res = await request(server).get('/api/key1');

            expect(res.status).toBe(200);
            expect(res.body).toBe('value1');
        });
    });
});

The resulting data looks like this:

[

  {

    id: '1647263665426-0',

    message: [Object: null prototype] { key1: 'value1' }

  }

]

My route handler code:

        const result = await redisClient.get(key);
        
        console.log(result);

        if(result && result[0] && result[0].message)
        {
            res.send(result[0].message[`${key}`]);
        } else {
            res.status(404).send("Key not found.");
        }

Is there a reason result[0].message['${key}']) or result[0].message.key does not work? What is the correct way to get the 'value1' from this returned object from Redis?

Answer 1

Turning the response for node-redis to a valid object allowed me to return the value I expected to.

const resultObject = JSON.parse(JSON.stringify(result[0].message));
res.send(resultObject[key]);
