Yes I noticed the same. I'm investigating that now. I believe that is a separate issue.

Update, looks to be caused by a very old version of colors https://github.com/Filirom1/findup/blob/master/package.json#L17 depended on by a very old findup package used in diagnostic-languageserver. https://github.com/iamcco/diagnostic-languageserver/blob/master/src/common/util.ts#L9. I guess it should be switched to use the more popular find-up package https://github.com/sindresorhus/find-up#readme.
