Failed to write manifest file.Error Domain=NSCocoaErrorDomain Code=640 "You can’t save the file “manifest.json” because the volume “Data” is out of space."

What happened?

I got this error logged in Sentry.

Failed to write manifest file.Error Domain=NSCocoaErrorDomain Code=640 "You can’t save the file “manifest.json” because the volume “Data” is out of space."

All of users have at least 100mb free memory.

I assume, that the problem is the size of manifest file reached the limit. But, I can't find any info about known limits of manifest.json file on ios and there is no information in documentation or elsewhere how to increase the size limit.

Version

1.19.3

Steps to Reproduce

Run an application and save a lot of data on user login

There's no limit for manifest file. It seems like there's not sufficient space to store app related data anymore. Here's the error you see https://developer.apple.com/documentation/foundation/1448136-nserror_codes/nsfilewriteoutofspaceerror

I just checked and figured out that we use only around 750 bytes of data stored in AsyncStorage. Still cannot understand how it's possible to run out of space.

It might be that users are low on total amount, hence the issue. For values larger than 1MB, AsyncStorages on iOS stores them in a separate file (for each item) - does your calculation cover this?

MaratowKyryl commented 7 months ago

It supposed to. I'm using this solution to calculate the size of all key-values from storage:

I can't tell for sure it would show the total disk space used. I'm unable to tell why you got that error, but it is related to disk space available on device (not due to some limit of AsyncStorage)
