LocalStorage is used for the composer settings; I think this person has their browser set to deny cookie & localstorage requests.

It might be - generally my users aren’t the type to play with any type of setting.
If I had this:
> [@Include username with JavaScript error reports](https://meta.discourse.org/t/include-username-with-javascript-error-reports/24068):
>
> Is it possible to include the username (if the user is logged in) with JavaScript error reports? This would be very useful in following up on problems, devices, configurations etc.
I might know the user and track them down.
Or perhaps if the last 3 IP’s per-user were logged - a single IP is a bit pointless with so many people having multiple devices, 1 3G, 1 Wifi etc.
Or might be able to prove they are not a member.

I don’t find any QuotaExceededError in our logs at all, but they wouldn’t be related to a 500 error from the server.
If you deployed using the [standalone config](https://github.com/discourse/discourse_docker/blob/master/samples/standalone.yml), then the redis server is in the docker container (since everything is in there). Did you use standalone? Which size droplet did you use?

Just to confirm I’m still seeing them:

Good idea, see if we can repro this error with Safari in private mode, @neil.

The KeyValueStore object protects against throwing on first access, not all accesses. So we need to add try-catch to all its methods.

The user base for this particular Discourse installation is prominently aged mostly 40 to 65 years old…
… it would be a lot of inexperienced non-technical users slipping into “private mode”.

I can definitely reproduce this by using Safari on Mac in private mode and going to my notifications page (/users/neil/activity). Javascript console shows:
```plaintext
Error while processing route: user.notifications (2)
"QuotaExceededError: DOM Exception 22"
```
It isn’t being logged, but that’s how it happens.

While fixing [a bug](https://bbs.boingboing.net/t/bug-swiping-back-in-safari-causes-page-error/67286) I got rid of these `QuotaExceededError` errors 😉
