noopLanguages Error

Hi I am hosting LanguageTool on my own server and I getting this error in the log;
“Cannot consider noopLanguages because not in fastText mode: [en]”
It is coming from the file “LanguageIdentifier.java”, but when I try it out everything is working just fine locally. Can someone please guide me a way around to fix this error ??

LanguageTool - 5.4 is my version

I’ve described the installation of FastText on my website, but it’s in German. Maybe you can use a translator.
