Error connecting to Beadi

[EskCresh]

This might actually be an error in buttplug, I don't know enough to say.

When connecting with Beadi (which uses the V2 spec), the following messages are transmitted:

[{"RequestServerInfo": {
    "Id":1,
    "ClientName":"Beadi Client 'Localhost'",
    "MessageVersion":2}
}]

[{"Error": {
    "Id":0,
    "ErrorCode":3,
    "ErrorMessage":"{\"ButtplugMessageError\":{\"MessageConversionError\":\"Message V3(ServerInfo(ServerInfoV2 { id: 1, message_version: Version2, max_ping_time: 0, server_name: \\\"Intiface Server\\\" })) not in Spec V2! This is a server bug.\"}}"
}}]

Slightly prettified error message:

Message V3(
  ServerInfo(
    ServerInfoV2 {
      id: 1,
      message_version: Version2,
      max_ping_time: 0,
      server_name: "Intiface Server"
    }
  )
) not in Spec V2! This is a server bug.

It looks like it's trying to send a Message V3 in a V2 session? I think this might have been introduced in 2.6.x, as I used Beadi a few weeks ago and it was fine.

I'm using Intiface Central 2.6.2+28 on Windows.

Intiface logs:

Woah! That is probably an error in Buttplug's new message handling, yeah. Thanks for reporting it, I'll check this out soon and will link to the relevant bug over there.

It looks like this can affect V3 as well:

[{"RequestServerInfo":{"Id":1,"ClientName":"Unity Client","MessageVersion":3}}]

[{"Error":{"Id":0,"ErrorCode":3,"ErrorMessage":"{\"ButtplugMessageError\":{\"MessageConversionError\":\"Message V2(ServerInfo(ServerInfoV2 { id: 1, message_version: Version3, max_ping_time: 0, server_name: \\\"Intiface Server\\\" })) not in Spec V3! This is a server bug.\"}}"}}]

But some clients work fine:

[{"RequestServerInfo":{"Id":1,"ClientName":"Buttplug Interactive Editor","MessageVersion":2}}]

[{"ServerInfo":{"Id":1,"MessageVersion":2,"MaxPingTime":0,"ServerName":"Intiface Server"}}]

As best as I can tell, this is consistent by client whether it works or fails. Seemingly, most other V2 clients work fine. I've only found one other V3 client (Wholesome Club Extensions), which also fails.

Okay, not sure what to make of this. Everything I tested earlier that failed, seems to work now. I don't know of any material changes to my setup that could have affected this.

... Huh. That is super weird, 'cause this sounded like a bug in 2.6.1 that I fixed in 2.6.2 and I thought was happening again. I'll still leave this open until I can verify locally.
