How to change/edit a static field value

[KWINEKO]

// API
class WebAPI.Protocol : System.Object
{
    static System.String address= "http://localhost:8002";
    ......
    static WebAPI.IContext DevelopmentCatalog();
    static System.Void OnDevelopmentCatalogCallback(WebAPI.IContext context);
    static WebAPI.IContext DevelopmentGet(System.Int64 recordKey);
    static System.Void OnDevelopmentGetCallback(WebAPI.IContext context);
    ......
}

Hello, I'm trying to change/edit fields in a class.
I read the discussion in #254, but is not for the static field.
If I edit the value directly, then will cause an error.

Protocol.field<Il2Cpp.String>("address").value = Il2Cpp.string("http://localhost:8024")

The error:

il2cpp: cannot write the value of field address as it's thread static or literal
    at set value (il2cpp/structs/field.ts:96)
    at <anonymous> (agent/index.ts:34)
    at <anonymous> (il2cpp/structs/thread.ts:92)
    at call (native)
    at <anonymous> (il2cpp/structs/method.ts:328)

Is there any way to modify thread static fields?

In theory, yes, there is.
Unfortunately I couldn't find a decent/working way to do that, yet.

However, you could do some hardcoding and you'd be fine. Take a look here

frida-il2cpp-bridge/src/il2cpp/structs/thread.ts

Line 119 in ae7ef9e

tryLocalValue(klass: Il2Cpp.Class): Il2Cpp.Object | undefined {

to see how I look for thread local values

Thank you, I roughly understand how you get the local value by Frida.

I have temporarily chosen to modify "global metadata.dat" to implement it.
Because I don't know how to modify the value while the program is running.
(I probably need to learn more about Frida hook)
