Shiny.onInputChange不是函数,奇怪的错误

首先,我在StackOverflow上找到了another topic about that error,但它并没有帮助我。

我试图在用户登录(或退出)我的网站时告诉Shiny,但我收到以下错误:

  

lwd.js:8 Uncaught(in promise)TypeError:Shiny.onInputChange不是函数       在LoginWithDiscord._onlogin(lwd.js:8)       在LoginWithDiscord.init(lwd.js:39)       在(指数):24

我真的不明白为什么,因为我使用SHINY。我在我的工作机器上尝试了相同的方法,效果非常好。

有一些我的代码,如果你想要更多只是问:)

this._onlogin = () => {
      let user = discord.fetchUser();
      Shiny.onInputChange('discordupfp', user.avatarURL);
      Shiny.onInputChange('discorduid', user.id);
      Shiny.onInputChange('discordusername', user.username);
    };
    this._onlogout = () => { 
      Shiny.onInputChange('discord-logout', 1);
    };

server.r:

 discordpfp = NULL
  discorduid = NULL
  discordusername = NULL
  lang = "us"


  observeEvent(input$discordpfp, {
    userpfp = input$discordpfp
  })

  observeEvent(input$discoruid, {
    discorduid = input$discorduid
  })

  observeEvent(input$discordusername, {
    userpfp = input$discordusername
  })

  discordarea = reactive({
    if(is.null(discorduid)){
      #No problem on showing my id
      tags$button(onClick="discord.login('342488102318637059', Scope.Identify)", class="login-button", "LOGIN")
    } else {
      tags$img(
        src=discordpfp,
        class="discord-image",
        width="75"
      )
      div(id="poupup-element",
          div(class="discord-poupup",
              tags$button(onClick="discord.logout()", class="logout-button", "LOGOUT")
          )
      )
    }
  })

  output$discordarea = renderUI({
    return(discordarea())
  })

  observeEvent(input$discordlogout, {
    discordpfp = NULL
    discorduid = NULL
    discordusername = NULL
    lang = "us"
  })
