Using mcr.microsoft.com/windows/servercore:ltsc2019 as the base image it is fine! Also you might want to consider using mcr.microsoft.com/windows/nanoserver:1809 since your application is nodejs.
Regarding the issue, the call to modify the compute system (the container) is when we attach the network adapter to it. I don't know why it failed but I recommend to open a support ticket, so we can investigate more about this problem.
