When starting up NativeScript Sidekick, I am presented an exception from the Windows stating the following (this error message also shows up in the output Errors in Sidekick): UnhandledPromiseRejectionWarning: ReferenceError: primordials is not defined (for easier reading the full stack trace of the error can be found at the bottom)
I have literally not done anything except install NativeScript Sidekick and open the application.
How do I resolve this issue?

More information from the console:
NativeScript Sidekick version: 1.16.2-v.2019.3.13.12
Dependencies versions: NodeJS: 12.1.0, npm: 6.4.1, NativeScript CLI: 5.3.4.
It turns out that NativeScript Sidekick must be using gulp 3.
I found this answer on StackOverflow talking about a similar issue, but not related to NativeScript Sidekick.
Must sure that your current installed node version is not 12, because node v12 and gulp 3 do not work together, as you can see here
To check your node version run the following in Terminal:
$ node -v
Since we can't change the gulp version of NativeScript Sidekick ourselves, the best solution is to downgrade the node version.
At the time of writing this the Latest LTS version is 10. Downgrading to this version resolves the exception error message.
