We used to use ncc compier to compile our node js server as a single executable. However once we upgraded nodejs version to 10.16.2 this was completely broken which caused UI to be broken.
We have temporarily removed ncc compiler to unblock UI usage. We need to be able to fix ncc compiler or manually compile the node server ourselves.
We now build all static assets to one common directory under the express server and build SDK based off it. This should fix the problem of incorrect static asset paths.
