Nodebb build error after updated translation files

[ckubs]

Tried to update some json files from translations folder of my language and I got the following error trying to build and restart Nodebb. Even after I reverted back the files I still got the error. If someone has any clue about this the help is much appreciated.

If you were updating the files, then it sounds like a syntax error in a file you changed.

Can you paste the contents of that file?

To find which files are erroring, add

console.error('json error in file', path.join(coreLanguagesPath, lang, namespace + '.json'));

Before each of the following lines of the linked file:

Line 108: https://github.com/NodeBB/NodeBB/blob/master/src/meta/languages.js#L108

Line 140: https://github.com/NodeBB/NodeBB/blob/master/src/meta/languages.js#L140
