Error on app reopen after an update is installed

[koraykupe]

Hello,

I get that error when I add a new release using release command and close the app and reopen on iOS simulator. I test it on local. tns build ios command is successful.
What could be the cause of the error?

Tried both on ON_NEXT_RESUME and IMMEDIATE install modes. I test the app while tns run ios --emulator --no-watch --no-hmr command is running. It only happens sometimes.

What's the exact command used to release a new AppSync version?

nativescript-app-sync release myappname ios

[EddyVerbruggen]

Hmm strange. The stacktrace seems to indicate you've used the "diff" feature..
Perhaps you're not using the latest version of the plugin?

In any case: is there a way for me to reproduce this? You mentioned "It only happens sometimes." so I hope you can narrow it down to a useful reproduction path.

[koraykupe]

I've checked and it's v1.0.7
Actually it happens most of the time, and only for iOS probably. My colleague works on the same project, but test Android side on a Windows machine and he don't get the error. This is an in-house project, but I will check if I can share it with you to test. I will also try to check it for Android on my own dev environment.

[EddyVerbruggen]

I'm pretty sure this is platform specific so no need to test Android.

Did you also test on a real device? The simulator filesystem is quite different from a real device so it would be interesting to know if you see the same problem there.

We're seeing this issue on our end big times:

NativeScript encountered a fatal error: NSErrorWrapper: Le dossier « app » n’existe pas.
 at copyEntriesInFolderDestFolderError(file:///app/vendor.js:1:1930458)

It fairly present but its not always reproductible apparent, which is super annoying, never seen it while developing

that name is super awkward as well, is this just a file format error ? (could be since I'm seeing n’existe instead of n'existe)

[AnthonyLenglet]

ok we fixed it on our end, it was caused by our last deployment being for version 3.3.3 only but being deployed as 3.3, so the people on version 3.3.4 (version update which came from the app store this time) were getting it and it was crashing the app on startup

the fix was to remove the deployment, it sucks a bit but we used it for hotfixes only and they came out in a full fledged release later on so it was fine for us 😄
