Invalid argument type when trying to pass EX into set function

[Gustaf Dahl]

When I try to set an expiration on my key redis throws a TypeError: Invalid argument error. I've basically copied the docs.

Environment:

• Node.js Version: v18.12.0
• Redis Server Version: 6.2.7
• Node Redis Version: 4.5.1
• Platform: Fedora 34

await redisClient.set(`test`, `test`); // Works

await redisClient.set(`test`, `test`, {}); // Does not work

await redisClient.set(`test`, `test`, { // Does not work
    EX: 10,
  });

Error:

maybe the client is in legacy mode?

[Gustaf Dahl]

I've tried it both with legacy mode and without

[Leibale Eidelman]

this script does not work (it should log "OK")?

import { createClient } from 'redis';

const client = createCilient();

client.on('error', err => console.error('Redis Client Error', err));

await client.connect();

console.log(
  await client.set('key', 'value', {
    EX: 10
  })
);

[Leibale Eidelman]

one more thing, can you please try this (just in case its v3 or in legacy mode):

redisClient.set(`test`, `test`, 'EX', '10');

[Gustaf Dahl]

Sorry for late response.
The attached script above with EX passed in an object worked. What I think happened is that I forgot to save my file when I removed legacy mode from the create client config...

Closing this issue as it has been resolved.
