Hi  
We are using Openvidu docker container along with the recording for the development. Recording works perfectly fine with the mode “individual” recording but, as soon as we start recording with mode as “COMPOSED”, getting “500” response.

Getting below error in the logs:

```

1. Which version of OV do you have? CE/PRO
2. What instructions did you follow deploy it?
3. What values do you have configured in /opt/openvidu/.env file?

Regards

@cruizba It’s OpenVidu CE 2.16 standalone docker dev image: [Docker Hub](https://hub.docker.com/r/openvidu/openvidu-server-kms)

The rest Ganesh will have to fill-in on Monday.

Thanks.

(Edit: We’re colleagues.)

1. Openvidu 2.16 CE (docker [image](https://hub.docker.com/r/openvidu/openvidu-server-kms) )
2. We are using docker container to develop application. we are following 4th step mentioned [here](https://docs.openvidu.io/en/2.16.0/tutorials/openvidu-recording-java/).
3. As this is docker container, no .env file is used. Just passing parameters like OPENVIDU\_RECORDING, OPENVIDU\_RECORDING\_PATH

So this happens locally while developing? Which OS are you?

Please update to latest 2.17 version. We have fixed several bugs related with COMPOSED recording.

If you still experience issues, please shared a full OpenVidu logs with us.

Hi @Ganesh_Patil

I’ve tested the system with WSL2 and Hyper-V, the same tutorial and everything is working as expected. You have something wrong in your Docker installation or maybe you’re running the container differently.

I would suggest to check the way you’re running the container, and to update Docker Desktop.  
I also suggest to use WSL2 in Docker Desktop which works and perfomce better.

Use the command EXACTLY as it is in the documentation:

```auto
docker run -p 4443:4443 --rm \
    -e OPENVIDU_SECRET=MY_SECRET \
    -e OPENVIDU_RECORDING=true \
    -e OPENVIDU_RECORDING_PATH=/opt/openvidu/recordings \
    -v /var/run/docker.sock:/var/run/docker.sock \
    -v /opt/openvidu/recordings:/opt/openvidu/recordings \
openvidu/openvidu-server-kms:2.17.0

```

Regards

Note: Use `OPENVIDU_RECORDING_PATH=/opt/openvidu/recording` and the volume `-v /opt/openvidu/recordings:/opt/openvidu/recordings`, don’t change those parameters.

Tried above command as it is. Running docker with WSL-2 enabled. Tried same setup on another windows 10 machine. Still I could not start recording with “COMPOSED” option.

Check that your docker daemon is also using the WSL-2 backend.

Additional Note: Is your machine somehow limited on downloading dockerhub images? It seems like the `openvidu/openvidu-recording:2.17.0` can not be found. Maybe if you pull this image from the WSL configured in this machine, you will be able to start recordings.

OpenVidu downloads the recording image if it is not found in the system, it should be downloaded on first run. Can you share to me the startup log of the `openvidu/openvidu-server-kms` image? That’s kind of strange.

Yes, It’s using a WSL2 based engine.

As “INDIVIDUAL” recording is getting started so it must be pulling a recording docker image. will send the start logs

Can you open a WSL2 terminal (the one you’re using with Docker, in case you have more than one distributions) and execute `docker pull openvidu/openvidu-recording:2.17.0` and try again?

Even though “Use the WSL 2 based engine” is enabled, not using any additional “disros”.
