I am getting this error when trying to run my game. Any1 know why this error comes and way to rectify it.
I have some players reporting they’re now getting this as well after an update (Unity version didn’t change) - they’re using FF/Win7
We’ve run into this as well - it’s related to caching/storage; I’m not 100% sure how we fixed it - but it did eventually go away on it’s own after a while.
After digging into this a little more my understanding is that websites get 50mb of caching allowed, if you go over that then the expected behavior is to display an error and give the option to increase the storage quota. As far as I can tell from my players they’re not getting the option to expand local storage quota which (i guess?) is a browser bug rather than anything Unity related. ‘Fixes’ are to get the user to force clear their cache or to manually set it to a higher limit.
Update on this issue - QuotaExceededError can also be thrown by use of Indexed DB - indexeddb - Storage limits on Chrome browser - Stack Overflow which is where Unity will try to cache files if ‘data caching’ is toggled on in publishing settings
tl;dr - error will get thrown if trying to use ~6% or more of the users available hard disc space.
Given that this op failing (data caching to indexedDB) I feel like Unity should be able to handle the error rather than the game failing to run. Would be good to get confirmation that this is really what’s happening from Unity folks!
Quota limit is a bit tricky because the rules for it vary across different browsers and browser versions. If the access to the indexedDB occurs during initial loading process when the .data file is being cached, then it might be indeed possible to recover from the failure, however if access occurs during LoadFromCacheOrDownload, then recovery might become nontrivial. Personally I have never encountered this error message myself. If this error occurs quite often in your specific use case, do you think it would be possible to find a reliable way reproduce it?
Thanks alex … I’ve never seen it personally either - I’m getting this bug report from a few players out of thousands. The players that it happens for it happens every single time they try to open the game.
It sounds like in order to repro you’d need to fill up your HD with stuff until there was very little space left to allow the data caching to work. I spent some time trying to repro this and was completely unable to. Mystery remains.
For info, it happen when you use “data caching” in your build. You can reproduce it easily in firefox. In your firefox options, set “History” to “Do not save history” and you get :
And a popup javascript error. But if you click it, the game run fine.
We got the same message in chrome, but without the javascript popup error.
It will be fine to have a way to remove this error, because some players will close the page just because of this javascript error.
I just started getting this pop-up error only in Firefox, when ironically, I was working on reducing and optimizing filesize. My Release folder was 9.5mb, and then despite shrinking to 7.4mb, the error was appearing.
It appears Aurigan is right about disk space:
I have less than 6% of free space… Now as I write this, I am deleting some large files I no longer need …
… now have 8% free disk space. Let’s try this again…
Whatta ya know, the error is gone!
