SpecFlow报错objectContainer不存在 如何正确初始化ObjectContainer

• 异常表现：使用SpecFlow框架运行UI自动化测试时，本地环境直接执行测试无任何报错，将测试项目上传至TFS流水线执行时触发错误。
• 本地复现结果：调整配置后已在本地复现该问题，错误定位在自动生成的NUnit.Assembly文件中，错误提示为："objectContainer"不存在于当前上下文。
• 错误参考截图：

StepsBase基类实现代码 #

using BoDi;
using InternetBanking.Tests.Helpers;
using NUnit.Framework;
using OpenQA.Selenium;
using System;
using TechTalk.SpecFlow;

namespace InternetBanking.Tests.Steps
{
    [Binding]
    public class StepsBase
    {
        public IWebDriver _driver;
        public string _IBUITestsUri;
        public string _urlLogin;
        public string _urlLogout;
        public string _urlHome;
        public string _userName;
        public string _password;
        public string _newPassword;
        public ScenarioContext _scenarioContext;
        public IObjectContainer _objectContainer;

        public StepsBase(ScenarioContext scenarioContext)
        {
            _scenarioContext = scenarioContext;

            _driver = _scenarioContext["driver"] as IWebDriver;
            _objectContainer.RegisterInstanceAs(_driver);
            _IBUITestsUri = _scenarioContext["IB-uitests-uri"] as string;
            _urlLogin = _scenarioContext["UrlLogin"] as string;
            _urlLogout = _scenarioContext["UrlLogout"] as string;
            _urlHome = _scenarioContext["UrlHome"] as string;
            _userName = _scenarioContext["Username"] as string;
            _password = _scenarioContext["Password"] as string;
            _newPassword = _scenarioContext["NewPassword"] as string;
            WDCustomFunctions.DefineDriver(_driver);
        }

提前感谢各位提供可行的排查思路与解决方案。
