Crash when commenting/merging

[orta]

In microsoft/TypeScript-Website#978 - here

Looking at the pull_request_review from sasurau4 in 'Translate 3 tsconfig files to ja' to see if we can merge

Changed files: 
 - /packages/tsconfig-reference/copy/ja/categories/Watch_Options_999.md
 - /packages/tsconfig-reference/copy/ja/intro.md
 - /packages/tsconfig-reference/copy/ja/options/fallbackPolling.md

Looks like a GitHub auth issue, but nothing changed on our side. I think?
