@totebo Metadata passed into match join attempt must be a flat JSON object of string keys to string values. In your case the code should not be:

```lua
metadata = {
    equipped_weapon_type = 1
}

```

Instead it should be:

```lua
metadata = {
    equipped_weapon_type = "1"
}

```

This is a constraint of the API because in Protocol Buffers its exposed as a map type:

Hope this helps.
