Query error for property with large String

[gurunbg]

I saved large string in database but when try to make query to get it I get error:

E/flutter (31707): [ERROR:flutter/lib/ui/ui_dart_state.cc(157)] Unhandled Exception: Exception: ObjectBoxException: find: 10098 Do not use vector-based find on 32 bit systems with big objects
E/flutter (31707): #0      checkObxPtr (package:objectbox/src/bindings/helpers.dart:15:5)
E/flutter (31707): #1      Query.find.<anonymous closure> (package:objectbox/src/query/query.dart:574:26)

E/flutter (31707): #3      Query.find (package:objectbox/src/query/query.dart:573:19)

This problem is only for x86 Android Emulator and it is ok for physical devices.
I founded very similar issue for Java Objectbox that was fixed 1 year ago - java issue

Thanks!

Yes, 32-bit support for large objects requires some special handling, calling visitor-based objectbox-c APIs instead of array-based ones and that's currently not implemented in the objectbox-dart lib code.

If anyone was interested to pick this up, I can help with more details/guidance and there's also objectbox-go which can be relied upon as the logic source, e.g. in box.go

As a workaround for the time being, you can use the x64 emulator.

Fixed in v0.6.2

I'm getting same error with langchain and openai embeddings

StorageException (StorageException: Do not use vector-based find on 32 bit systems with big objects (OBX_ERROR code 10098))

@mirkancal As the error message indicates, the vector functionality is currently only supported for 64-bit platforms. If you are running on a 64-bit platform, please open a new issue with more details, notably about the platform you are running your code on!

Side note: Flutter only supports 64-bit platforms now (with the exception of some older 32-bit ARM Android versions).

@greenrobot-team thank you, let me check if I set it to 32-bit somehow. I'm not sure how I can choose 32 bit iphone 16 pro emulator with ios 18.

I think the error message might be misleading in this case. Can you open a new issue with a full stack trace please?
