HarmonyOS鸿蒙Next中napi_call_function调用CanvasRenderingContext2D的方法为什么会发生崩溃呢

ArkTS:

private context: CanvasRenderingContext2D = new CanvasRenderingContext2D(this.settings);

XTest(this.context);

c++:

    size_t argc = 1;

    napi_value thisVar = nullptr;
    void* data = nullptr;

    if (napi_get_cb_info(env, info, &argc, argv, &thisVar, &data)) {
        return result;
    }
    
    napi_valuetype valueType = napi_undefined;
    napi_typeof(env, argv[0], &valueType);

    if (valueType != napi_object) return result;

    valueType = napi_undefined;
    napi_typeof(env, argv[0], &valueType);

    if (valueType != napi_object) return result;
    
    
    std::string cArr = "fillText";
    napi_value key;
    napi_status ok = napi_create_string_utf8(env, cArr.c_str(), cArr.length(), &key);
    if(ok != napi_ok) return result;

    napi_value callback = nullptr;
    ok = napi_get_property(env, argv[0], key, &callback);
    napi_typeof(env, callback, &valueType);
    if (valueType != napi_function) return result;
    
    
    napi_value xdata[4] = {nullptr};
