Error during opening of ObjectBox-Dart library on the macOS

[ksatalsin]

• existing issues : simmilar

When attempting to initialize the ObjectBox-Dart library without specifying a folder, an error occurs with an "Operation not permitted" (code 1) message. This is happening with the sandbox = ON in the entitlement runner file. The step with groups was done as described https://swift.objectbox.io/advanced/macos

• ObjectBox version: 2.0.0
• Flutter/Dart SDK: Flutter 3.7.12
• Null-safety enabled: y
• Reproducibility: always
• OS: macOS any
• Device/Emulator:

Steps to reproduce

1. Add the ObjectBox-Dart library.
2. Set sandbox mode to ON in the entitlements file by adding the following code:

<key>com.apple.security.app-sandbox</key>
<true/>

3. Attempt to open the ObjectBox-Dart library without specifying a folder in the code, like this:

final store = await openStore();

Expected behavior

Should be able to proceed without exception, because I am able to read/write data in the same folder

The docs you linked are for objectbox-swift. For Flutter you also need to pass the application group to Store, see the info box "For sandboxed macOS apps". (Note: it's also recommended to edit the entitlements files manually for Flutter apps.)

Edit: let me know if this does not fix your issue. Otherwise, this issue will automatically close in 2 weeks if there is no response.

Hi @greenrobot-team, thanks for the reply, I tried settings for the release with sandbox on and still got the same result:

and in the app

Thanks

Quoting the docs:

Note: Pick a short group identifier; there's an internal limit in macOS that requires the complete string to be 19 characters or fewer.

Without additional information, we are unfortunately not sure how to resolve this issue. Therefore this issue has been automatically closed. Feel free to comment with additional details and we can re-open this issue.

full string $(TeamIdentifierPrefix).$(PRODUCT_BUNDLE_IDENTIFIER)should be shorter or only the group id? If it first, shud I change my bundle id to shorter version? If I use $(TeamIdentifierPrefix)as the group id, I also get a black screen.

<key>com.apple.security.application-groups</key>
<array>
<string>$(TeamIdentifierPrefix)</string>

@DzianisMatveyeu The 19 character limit is for the whole string passed to openStore(macosApplicationGroup: 'FGDTDLOBXDJ.demo'). E.g. in this example FGDTDLOBXDJ.demo.
