Javascript 节点中的二进制数据已损坏或未正确读取

我有一个带有以下组件的React应用程序：

import React from 'react';
import PropTypes from 'prop-types';
import { isDelayN, isDelayS } from '../utils/api';

function IsDelayN (props) {
    isDelayN(props.sub, props.stop);
    if (props.stop === null) {
        return (null);
    } else if (isDelayN.noDelay) {
        return (<p>The next train will arrive in {isDelayN.noDelay} minutes.</p>);
    } else if (isDelayN.yesDelay <= 10) {
        return (<p>A {isDelayN.yesDelay} delay isn't that big a deal, right?</p>);
    } else if (isDelayN.yesDelay > 10 && isDelayN.yesDelay <= 15) {
        return (<p>Oof, you've got a {isDelayN.yesDelay} minute delay. You should let your boss/friends/Tinder date know you're going to be late.</p>);
    } else {
        console.log(isDelayN.noDelay);
        return (<p>So... The MTA's reporting a {isDelayN.yesDelay} minute delay for you right now. Tbh, wherever you're headed, you might as well call out sick.</p>);
    }
}

function IsDelayS (props) {
    isDelayS(props.sub, props.stop);
    if (props.stop === null) {
        return (null);
    } else if (isDelayS.noDelay) {
        return (<p>The next train will arrive in {isDelayS.noDelay} minutes.</p>);
    } else if (isDelayS.yesDelay <= 10) {
        return (<p>A {isDelayS.yesDelay} delay isn't that big a deal, right?</p>);
    } else if (isDelayS.yesDelay > 10 && isDelayN.yesDelay <= 15) {
        return (<p>Oof, you've got a {isDelayS.yesDelay} minute delay. You should let your boss/friends/Tinder date know you're going to be late.</p>);
    } else {
        return (<p>So... The MTA's reporting a {isDelayS.yesDelay} minute delay for you right now. Tbh, wherever you're headed, you might as well call out sick.</p>);
    }
}

export { IsDelayN, IsDelayS };

控制台还提供以下错误：

未处理的拒绝错误：Message.transit\u realtime.FeedMessage#decode:6中未知字段13的导线类型非法。当我在谷歌上搜索该错误消息时，我发现了这个问题（我在项目中使用的
mta gtfs realtime bindings
package在引擎盖下有
protobufjs
）。
protobufjs
的创建者解释说，“通常，类似这样的错误是由于二进制数据被破坏而导致的。关于该主题有一个wiki页面：

此外，关于如何手动检查二进制数据的两个示例如下：#55。“

不幸的是，我对读取二进制数据或Node了解不够，无法理解他建议的解决方案如何应用于我的项目。有人能给我一些见解吗
