Hi Linus, thank you for the contribution. This is actually a bug in Node 7.7.2 (nodejs/node#11761). We recommend you stick with 7.7.1 until that fix is published.

[LinusU]

Ahh, that's interesting, I was quite sure that it started working after I applied this patch 🤔 maybe I messed something else up... will check...

[NatalieWolfe]

Your patch bypasses the Node bug by passing null for the callback when no callback is provided instead of nothing. This just happens to be the one thing that Socket#connect code does check for: https://github.com/nodejs/node/blob/v7.7.2/lib/net.js#L942.

[LinusU]

Haha, yeah that explains it then 😄

[NatalieWolfe]

7.7.3 came out yesterday (https://nodejs.org/en/blog/release/v7.7.3/). Would you mind seeing if that version of node works for you?

[LinusU]

I'll check tomorrow 👌

[NatalieWolfe]

Just checking in if you've had an opportunity to test the newer version of Node?

[LinusU]

Sorry totally forgot about this, yes it seems to be working in 7.7.3, thanks for the help 👏

[NatalieWolfe]

Awesome! Glad it worked out. :)
