Deprecation warning during remote task

[kokujin]

Is there an explanation for this warning I get when I execute a remote task? "DeprecationWarning: Calling an asynchronous function without callback is deprecated."

Thanks

[pstadler]

Could you please provide a full stack trace?

I am having the same issue. I don't get a stacktrace for the DeprecationWarning, but here is the output of the command I am running. Of note is the error Error connecting. All configured authentication methods failed. for the remote command, but rsync was able to successfully transfer the files.

I have the same issue:

✈ Local task finished after 1.07 min
✈ Flightplan finished after 1.07 min
(node:55299) DeprecationWarning: Calling an asynchronous function without callback is deprecated.```

[pstadler]

Unfortunately, I don't see where this is coming from. Could you provide more context? node --version certainly helps, plus a little test flightplan.js on how to reproduce this would be good.

same issue from server msg: localhost ● ok ✈ Local task finished after 23 s ✈ Flightplan finished after 23 s (node:21945) DeprecationWarning: Calling an asynchronous function without callback is deprecated.

[DiederikvandenB]

Ah right, I think this might be the issue:

➔ node --version     
v7.7.4

I have the same problem: localhost ● ok ✈ Local task finished after 1.44 s ✈ Connecting to '...' (node:14168) [DEP0013] DeprecationWarning: Calling an asynchronous function without callback is deprecated. ● Error connecting to '...': All configured authentication methods failed

node --version v8.1.3

For the 'All configured authentication methods failed' error, See here: #41.

Ran into this issue on node v8.8.1

@chip My SSH keys are valid, this user can connect to remote with an alias, so #41 doesn't seem to apply.

Serhioromano's solution solved this for me. You need to add a privateKey property to the object literal in the server params. privateKey: '/home/user/.ssh/id_rsa',

Not sure why this is. Maybe there is a variation in how distros use SSH_AUTH_SOCK. For reference, local is Manjaro, remote is Arch.
