Error while generating struct #687

Closed AF-Source closed 1 year ago

AF-Source commented 1 year ago

Whenever I dump everything works but for some reason I get this error when it's trying to generate struct. In config, if I set 'GenerateStruct' to false, it works, however I need the struct. The error I get: System.InvalidOperationException: Sequence contains no matching element at System.Linq.ThrowHelper.ThrowNoMatchException() at Il2CppDumper.Macho64.MapVATR(UInt64 addr) in C:\projects\il2cppdumper\Il2CppDumper\ExecutableFormats\Macho64.cs:line 74 at Il2CppDumper.StructGenerator.ParseType(Il2CppType il2CppType, Il2CppGenericContext context) in C:\projects\il2cppdumper\Il2CppDumper\Outputs\StructGenerator.cs:line 542 at Il2CppDumper.StructGenerator.WriteScript(String outputDir) in C:\projects\il2cppdumper\Il2CppDumper\Outputs\StructGenerator.cs:line 430 at Il2CppDumper.Program.Dump(Metadata metadata, Il2Cpp il2Cpp, String outputDir) in C:\projects\il2cppdumper\Il2CppDumper\Program.cs:line 268 at Il2CppDumper.Program.Main(String[] args) in C:\projects\il2cppdumper\Il2CppDumper\Program.cs:line 102 I attached the archive with the metadata and executable file below archive.zip

Anything? If not, do you need me to provide anything else? EDIT: Il2Cpp Version 29 Metadata Version 29 Target Unity Version 2021.3 Il2CppDumper-net7-v6.7.32

After my testing I found that this is an error that should not occur. Are the executable and global-metadata.dat from the same version? Because I found that their modification time is quite different.

I'll check, but pretty sure it is. It dumps everything correctly and only structure failed to generated. I'll double check about that and see if that solves the issue.

I decrypted the app again and got a fresh .ipa, from there extracted the UnityFramework and metadata(which works successfully for the dump.cs file and the .dll inspection) but it still fails Initializing metadata...

If you need any further logs/information on my system, let me know.

Hi. Can I ask what the issue was with? I am genuinely curious from a developer perspective?

Perfare commented 1 year ago

In fact, I don't know what the reason is. This error should not exist. My practice is to let him not report the error.

how do I solve this error
