Facing problem with channel reconnect

hi guys,

I am having problem with reconnect ing channel. I call the channel.leave() method to leave the chanel. But when I try to reestablish the connection, I see the following events: connected -> disconnected.

This is piece of code I am using to reconnect:

 let ch = await Channel({
                ...params,
                role: params.role,
                port: params.port,
                existingChannelIdKey : channelId,
                offchainTx,
                sign: getTxCb(keyPair)
              })

where,

  • offchainTx : is the signed tx which I got when I had called leave()
  • existingChannelIdKey : is the channel id.

Also there is one more problem, I tried using this piece of code and it looks like it got reconnect but this time, the ch.id() is coming undefined on the event open…

let ch = await Channel({
                url: params.url,
                host: params.host,
                port: params.port,
                role: params.role,
                existingChannelId: channelId,
                existingFsmId: channelData.fsmId,
                offchainTx,
                sign: getTxCb(keyPair)
            })

So these are the sequence of activity I did and got stucked in 2nd time reconnection.

  • Created
  • Updated
  • left
  • reconnected
  • updated
  • left
  • reconnect [ERROR]

So when I left the channel for the second time, and tried reconnecting, I see ch.fsmId() as well as ch.id() both as undefined

Hey @dimitar.chain can you take a look, please?

Since at this point this is a SDK question, I summon @nduchak.chain. If it is a FSM issue, I will take over.

hey,
I will investigate this and get back to you as soon as it will be done.
But looks like that reconnection flow is broken in current implementation
