i keep having the client is closed operation

i checked the documentations and i added “client.connect()’ the error went didn’t show up but my api responses weren’t coming through i asked gpt and according to it the line i added was the issue.

const client = redis.createClient();
client.connect();

client.on("error", function (error) {
  console.error(error);
});



const setJWT = (key, value) => {
  console.log(typeof key,typeof value)
  return new Promise((resolve, reject) => {
    try {
      return client.set(key, value, (err, res) => {
        if (err) reject(err);
        resolve(res);
      });
    } catch (error) {
      reject(error);
    }
  });
};

const getJWT = (key) => {
  return new Promise((resolve, reject) => {
    try {
      client.get(key, (err, res) => {
        if (err) reject(err);
        resolve(res);
      });
    } catch (error) {
      reject(error);
    }
  });  
};  

const deleteJWT = (key) => {  
  try {  
    client.del(key);  
  } catch (error) {  
    console.log(error);  
  }  
};  
module.exports = {  
  setJWT,  
  getJWT,  
  deleteJWT,  
};  

when i tried the await method it’s the same issue
