I solved this issue.

@javadev Could you submit a PR to fix this, so that other Ukrainian users won't have the bug. Maybe we can patch this method:

generator-jhipster/generators/generator-base-private.js

Line 269 in d237bd8

updateLanguagesInMomentWebpackNgx(languages) {

Or maybe the UA locale should be renamed UK ?

@PierreBesson I found this bug only for React not for Angular.

[pascalgrimaud]

I confirm the issue.

Currently, we don't have the issue with Angular because the dependency moment-locales-webpack-plugin is different between Angular and React

For Angular:

• moment-locales-webpack-plugin: 1.0.5

For React:

• moment-locales-webpack-plugin: 1.0.7

Downgrading the moment-locales-webpack-plugin dependency in React to use the version 1.0.5 works.
