在Swift-iOS应用程序中使用Protobuf和JSON文件无法将JSON转换为Struct

我有一个json数据的.json文件（见下文）。我正在使用显示的代码从应用程序的本地文件加载数据

我希望了解我的json文件是否格式不正确，或者是否需要更改.Proto文件中的某些内容，或者代码是否不正确

我从serializedData try/catch中获得以下格式错误的Protobuf错误

致命错误：无法加载。来自主捆绑包的json.json:malformedProtobuf:file MyToyBox/ModelData.swift。来自主捆绑包的json:malformedProtobuf:file MyToyBox/ModelData.swift，第563行

从文件中

///二进制数据在某些方面存在格式错误，例如无效的导线格式///或字段标记。

    let data: Data

    do {
        data = try Data(contentsOf: fileURL)
    } catch {
        fatalError("Couldn't load \(fileURL.absoluteString) from main bundle:\n\(error)")
    }
    
    do {
        let response = try SeriesInfo(serializedData: data)
        
        guard let receivedFromJSON = try? SeriesInfo(jsonUTF8Data: response.jsonUTF8Data()) else{
            fatalError("Couldn't load \(fileURL.absoluteString) from main bundle:\n")
        }
        
        return receivedFromJSON
    }
    catch {
        fatalError("Couldn't load \(fileURL.absoluteString) from main bundle:\n\(error)")
    }
