Hi Team,

I’m getting invalid JSON of client data.  
{“clientData”:“Participant”,“participantId”:“0\_nfdk7jdpru8”,“type”:“CAMERA”}%/%{}  
Due to this nickname of remote participant not showing correctly.

Hi,

This is a remanent of a bad design decission that was took years ago, and in favor of not going through breaking changes it has remained that way: [Share data between users - OpenVidu Docs](https://docs.openvidu.io/en/2.25.0/cheatsheet/share-data/)  
If you provide participant metadata through both the client side (with openvidu-browser SDK) and server side (with REST API / Java SDK / Node SDK) then both strings will be separated by string **`%/%`**. You must parse it before accessing both JSONs.  
We will probably change this with a breaking change soon, becasue this makes no sense at all.

Best regards.
