Autorest: UnhandledPromiseRejectionWarning

[markti]

I've been using autorest for months to update my webapi client .NET Standard library that I use in my Xamarin app. I hadn't made an change in a while but did today. So I updated my swagger.json and re-ran my script. This time the script gave me the following error in its output:

What could be the cause? Its been working so well until now.

Node v12 not supported.

Go back to node v10 LTS

[bleroy]

12 is now LTS.

10.17.0 LTS which was released yesterday also throws this

I am observing the same behavior (which was also reported in #2919). The error is present on 10.17.0, not on 10.16.3. I bisected the regression to nodejs/node@85ce8ef19a. It appears that making fs.promises enumerable causes patchFilesystem in static-link to throw TypeError when it attempts to .bind it.

[fearthecowboy]

GAH! They backported it to the v10 stable LTS branch! ARRRRGH!

The good news, it's throwing this error on _exit_ ... so it will still physically work, but it'll throw the error.

I have a fix for the static-linker done -- I did it last week, but I didn't think I'd have to publish the main stable package again yet, but now I clearly do.

lemme go fix this now and republish. Gonna take me a few hours. Stick to 10.16.3 until I can publish an update.

[fearthecowboy]

I published a new version (2.0.4407) that doesn't crash on 10.17+ and 12.13+

give it a try, and yell if it's got more problems.

[kevinoid]

2.0.4407 works for me and does not print the error message. Thanks @fearthecowboy!

[MiYanni]

Closing as the issue has been resolved.
