InvalidOperationException: No properties in class, has linker stripped it? #3363

89trillion-zhixin · 2023-06-26T16:47:13Z

What happened?

I'm having problems using Realm, Realm cannot create LocalResData, LocalResData is in the assembly, and Realm Init is in other assembly.

Unity: 2020.3.38f1
Relam: 11.1.2
Build：IL2CPP, Android

I don't know how to solve this problem, can anyone help me?

Repro steps

After I build Android apk, this issue will definitely happen

Version

4.x

What Atlas Services are you using?

Local Database only

What type of application is this?

Unity

Client OS and version

Unity 2020.3.38f1

Code snippets

This is LocalResData

using Realms;

namespace Functions.Core.Realms.RealmModel
{
    [Preserve(AllMembers = true)]
    public class LocalResData : RealmObject
    {
        [PrimaryKey, Preserve(AllMembers = true)] public int JoinId { get; set; }
        [Preserve(AllMembers = true)] public long Num { get; set; }

        public static void Init()
        {
        }
    }
}

This is init

public static void New(string userId)
{
    RealmConfiguration config = new RealmConfiguration($"{Application.persistentDataPath}/{userId}_JPG");
    config.Schema = new Type[]
    {
        typeof(LocalResData),
        typeof(TopicData)
    };
    config.EncryptionKey = Convert.FromBase64String(Url);
    config.SchemaVersion = 0;
    Realm = Realm.GetInstance(config);
}

I already have link.xml

<linker>
    <assembly fullname="Functions.Core" preserve="all"/>
</linker>

### Relevant log output

nirinchev · 2023-06-27T11:11:24Z

Hey, do you have a minimal repro project you could share with us? That'll help quite a lot to pinpoint where the issue stems from.

avolkangursel · 2023-07-07T10:18:32Z

Hello, we are also experiencing the same issue, and it is critical for us. Currently, we cannot release an update to our game due to this error. Unfortunately, I cannot share the project, but I can provide more details about the issue we are facing.

We didn't have this issue before. We simply updated the Realm SDK, and this problem started occurring. We started experiencing this problem after updating the Realm SDK from version 11.0.0 to version 11.1.2.

Unity: 2021.3.26f1
Realm: 11.1.2
Build: IL2CPP, Android, iOS

Important Note: We use CI/CD for publishing updates. While we don't encounter any issues when building locally, we face this problem when building from another device using "batch mode."

Both when building and when selecting "Weave Assemblies" from the "Tools" menu, we receive an error.

Could not analyze the user's assembly.

This looks similar to #3364. Can you try if the package linked in the last comment alleviates the issues for you?

Hello, I tried the package. The "Could not analyze the user's assembly." error seems to be resolved, but unfortunately, we still receive the "InvalidOperationException: No properties in class, has linker stripped it?" error when building with "batch mode" on the CI/CD machine.

nirinchev · 2023-07-07T14:28:25Z

Can you share the logs when building on CI?

avolkangursel · 2023-07-07T16:23:56Z

Unfortunately, for privacy reasons, I cannot share the entire log of the project. Instead, I will try to reproduce the issue with a test project. If I can reproduce it, I can directly share the project.

Additionally, I can examine the log file on the CI machine and share the information I found. For example, when the API Updater runs, I see the following messages related to Realm:

[API Updater] Assemblies not requiring updates:
…
[API Updater] Packages/{package name}/Runtime/ThirdParty/Realm/Editor/Realm.UnityWeaver.dll (stdout below):
[AssemblyUpdater] Removing 'mscorlib, Version=4.0.0.0, Culture=neutral, PublicKeyToken=b77a5c561934e089' from 'Realm.UnityWeaver' list of referenced assemblies (no type referencing this assembly was found).
[API Updater] Packages/{package name}/Runtime/ThirdParty/Realm/Runtime/Realm.UnityUtils.dll (stdout below):
…

By the way, we are using the Realm SDK by including it in a custom package that we have created internally. Therefore, the file paths for the Realm DLLs are located within the Packages folder.

After the Tundra build, the error message below appeared precisely 94 times. It starts with the message
*** Tundra build success (18.56 seconds), 961 items updated, 1062 evaluated.

Then, in succession, the following error message occurs 94 times.

nirinchev · 2023-07-07T16:44:26Z

Thanks, that's quite helpful. I think I know what's going on - I've created a PR with a proposed fix and will give you a package to try as soon as CI builds it.

avolkangursel · 2023-07-07T16:53:33Z

Thank you very much. I can try it when the package arrives.

nirinchev · 2023-07-07T17:49:59Z

Can you try this package and see if that still causes the error on CI?

avolkangursel · 2023-07-07T19:14:04Z

I apologize for the delayed response. I tried the package, and it seems that the issues have been resolved. Thank you very much.

nirinchev · 2023-07-07T22:26:15Z

Thanks for confirming! We'll schedule an official release with the bugfix shortly.
