il2cpp: couldn't invoke method .ctor as it needs 2 parameter(s), not 1

[pfyy]

i was doing the examples to create a new struct, however, i didn't succeed

error log:

il2cpp: couldn't invoke method .ctor as it needs 2 parameter(s), not 1
    at invokeRaw (/node_modules/frida-il2cpp-bridge/dist/index.js:2631)
    at maybeObjectHeaderSize (/node_modules/frida-il2cpp-bridge/dist/index.js:2794)

meanwhile, i found your code relies on the ctor signature of System.RuntimeTypeHandle:

        const struct = Il2Cpp.corlib.class("System.RuntimeTypeHandle").initialize().alloc();
        struct.method(".ctor").invokeRaw(struct, ptr(0xdeadbeef));

however, at least for this game, it is not the signature you are looking for:

il2cpp dump:

// mscorlib
struct System.RuntimeTypeHandle : System.ValueType, System.Runtime.Serialization.ISerializable
{
    System.IntPtr value; // 0x8
    System.Void .ctor(System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context); // 0x03b5e995
    System.IntPtr get_Value(); // 0x03b5e9d9
    System.Void GetObjectData(System.Runtime.Serialization.SerializationInfo info, System.Runtime.Serialization.StreamingContext context); // 0x03b5eb77
    System.Boolean Equals(System.Object obj); // 0x03b5ece0
    System.Int32 GetHashCode(); // 0x03b5ed0f
}

the signature requires an extra context args, which breaks the struct related calls

the same is still true even if you don't use the new fancy calls for unboxed structs:

[pfyy]

the latest version of your project is used, which is 0.9.1 at the time of writing

and for clarity of error log, here is the #2794 of your code

Thanks for reporting. I'll try to take a look at it, but it's unlikely to happen soon as I don't have much free time. What's the Unity version, game id and platform?

But oh, did you try with:

vec.method(".ctor", 2)

?
