I’m trying to do a simple macro with a site that beautify code,

1- paste a text in input box to the left

2- Click “Beautify” button

3- Copy the result of output box to the right

This is my current code but I’m getting run time error 91 Object variable or With block variable not set for line inputBox.innerText = ...

Sub Test()
Dim url As String
Dim oHttp As New MSXML2.XMLHTTP60
Dim inputBox As Object, outputBox As Object
Dim myBtn As Object

    url = "https://www.tutorialspoint.com/online_ruby_formatter.htm"

    oHttp.Open "GET", url, False
    oHttp.send
    
    Dim html As New HTMLDocument
    html.body.innerHTML = oHttp.responseText

    'Inserting code to beautify
    Set inputBox = html.getElementsByClassName("ace_content")(1)
    inputBox.innerText = "if" & vbCr & "sometext" & vbCr & "elsif" & vbCr & "other text" & vbCr & "else" & vbCr & "last text" & vbCr & "end" & vbCr
    
    'Click button to beautify
    Set myBtn = html.getElementsByClassName("l-btn-text")(7)
    myBtn.Click

    'Get text of beautified code
    Set outputBox = html.getElementsByClassName("ace_content")(0)
    Debug.Print outputBox.innerText
    
End Sub
