Hello, I’m using Nakama sdk 3.9.0 for Unity game and now adding groups functionality. I just run the example from your website to get user groups, but for some reason it returns nil fields (name, id…). At Nakama Console I see that groups have ids and names, but function is not working correctly.

Code I’m using:

local nk = require(“nakama”)

local function UpdateGroupMetadata(context, payload)

```
local user_id = "8686545f-af1d-4e44-b045-44f0a5931136"
local groups = nk.user_groups_list(user_id)
for _, g in ipairs(groups) do
  local msg = string.format("User has state %q in group %q", g.state, g.name)
  nk.logger_info(msg)
end
return nk.json_encode({["success"] = true})

```

end  
nk.register\_rpc(UpdateGroupMetadata, “UpdateGroupMetadata”)

Result in terminal:

In Nakama Console I see all groups information including ids and names.

Please help…

@electricpunch Can you share the Nakama server version as well? Your issue is with server-side code, so it would help to know the server version.

Just tried to clear all data and install the server with latest docker-compose.yml file (cockroach:latest-v23.1, nakama:3.19.0), the same problem…

Each result has 2 top-level fields: `state` which is the membership type of the user to the group (member, admin etc) and `group` which is the group data itself.

The correct way to access the group fields in your iteration is:

```lua
local msg = string.format("User has state %q in group %q", g.state, g.group.name)

```

We’ll make sure the documentation correctly reflects this. 🙇‍♂️
