6 years ago Hello @daniel84,
It is possible that this error occurs because the file src/environments/environment.prod.ts is missing.
So please copy the file src/environments/environment.dev.ts.example to src/environments/environment.prod.ts and fill it according to your server configuration.
note: @RomainSanchez the file src/environments/environment.prod.ts.example is not up to date so don't use it.
Hope this helps.
