Argument of type '(nsp: any) => RedisAdapter' is not assignable to parameter of type 'AdapterConstructor' socket.io version 4.6.0

[EternalC0der]

The bug
I've been using @socket.io/redis-adapter @8.1.0 with socket.io @4.5.4 without any issues.
Now that I upgraded to socket.io 4.6.0 it suddenly stopped working and I'm getting an error.

As it is mentioned in the documents (https://socket.io/docs/v4/redis-adapter/),
This is how my code looks like (simplified for the sake of this issue):

// Typescript
const pubClient = createClient({ url: "redis://localhost:6379" });
const subClient = pubClient.duplicate();

await Promise.all([pubClient.connect(), subClient.connect()]).catch((e) => {
    console.log(`${chalk.hex(pallette.red)('Redis error:')}`, e.message || e)
})

io.adapter(createAdapter(pubClient, subClient)) // <= Error at this line

And I'm getting an error with io.adapter(createAdapter(pubClient, subClient)):

Argument of type '(nsp: any) => RedisAdapter' is not assignable to parameter of type 'AdapterConstructor'.
  Type '(nsp: any) => RedisAdapter' is not assignable to type '(nsp: Namespace<DefaultEventsMap, DefaultEventsMap, DefaultEventsMap, any>) => Adapter'.
    Type 'RedisAdapter' is missing the following properties from type 'Adapter': _encode, persistSession, restoreSession

To Reproduce
Example in the docs (https://socket.io/docs/v4/redis-adapter/) with latest versions of @socket.io/redis-adapter, socket.io, redis and typescript gives a type error.

Platform:

• Device: Desktop
• OS: Windows 11
• Nodejs: 16.19.0

Hi! It seems you have two different versions of the socket.io-adapter package, which is included by both socket.io and @socket.io/redis-adapter. Could you please check?

$ npm ls socket.io-adapter

We have tried to fix this in version @socket.io/redis-adapter@8.1.0, with socketio/socket.io-redis-adapter@f07ff7b, but it does not seem to be sufficient.

As a workaround, could you try running npm dedupe?

having the same issue with @socket.io/mongo-adapter@0.2.1

[darrachequesne]

@quipo this should be fixed in latest release of the MongoDB adapter: 0.3.0

I'm having the same issue with @socket.io/cluster-adapter@0.2.1 too.

[faradaytrs]

Yeah not fixed

I'm having the same issue with @socket.io/cluster-adapter@0.2.1 too.

Same I tried running npm dedupe but still have the same issue also tested the latest socket.io version 4.6.1, I have some details on this closed issue. #4621 (comment).

+-- @socket.io/cluster-adapter@0.2.1
| `-- socket.io-adapter@2.4.0
`-- socket.io@4.6.1
  `-- socket.io-adapter@2.5.2

For future readers:

We have added socket.io-adapter in the list of peer dependencies of the other adapters, in order to match the version which is imported by the socket.io package:

• @socket.io/redis-adapter@8.1.0
• @socket.io/mongo-adapter@0.3.0
• @socket.io/postgres-adapter@0.3.1
• @socket.io/cluster-adapter@0.2.2

So this issue does not happen in the future. Please reopen if needed!
