Wiki.js breaks and displays blank page when cookies are denied

[fireundubh]

Using Firefox 73, setting the browser to deny all cookies breaks Wiki.js v2.1.x and a blank page is displayed to the user.

Another user reported the same issue in Chrome when that browser is set to deny all cookies.

I reproduced the issue in Vivaldi by setting the browser to deny all cookies. I could not reproduce the issue in Vivaldi when using uMatrix to block cookies, however. In that case, the browser may be accepting the cookie, which is good enough for Wiki.js, but the extension intercepts and discards it.

Wiki.js should not require a cookie for unauthenticated guest users.

A cursory look at the source suggests that you're assuming the jwt cookie is available, but if it's not (as it wouldn't be when cookies are denied at the lower browser level), the code that operates on the jwt cookie is probably just throwing exceptions. There doesn't seem to be any logging to file so I can't check that.

The issue appears to be cookie-adjacent and not actually a cookie. By disabling cookies you are also disallowing access to local storage. At least one of the dependencies here (namely i18next-localstorage-backend) relies on local storage to function. Without that it just throws an error and never gets around to showing anything on the page.

I wouldn't categorize this as a code issue in this project.

Most likely an issue with the localstorage indeed. A bug nonetheless...
