Google Appscript: Output of parsing function for a Table of Contents results in an array of objects not in the correct format. Help appreciated

Question

I am currently trying to parse the url and text from a table of contents on a google doc and write them into a table on google sheets.

So far I have been successful in getting the text and the url using the following code modified from the top answer in this post (How to use .findElement(DocumentApp.ElementType.TABLE_OF_CONTENTS) to get and parse a Document's Table of Contents Element)

function parseTOC( docId ) {
  var contents = [];
  var doc = DocumentApp.openById(docId);

  // Define the search parameters.
  var searchElement  = doc.getBody();
  var searchType = DocumentApp.ElementType.TABLE_OF_CONTENTS;

  // Search for TOC. Assume there's only one.
  var searchResult = searchElement.findElement(searchType);

  if (searchResult) {
    // TOC was found
    var toc = searchResult.getElement().asTableOfContents();

    // Parse all entries in TOC. The TOC contains child Paragraph elements,
    // and each of those has a child Text element. The attributes of both
    // the Paragraph and Text combine to make the TOC item functional.
    var numChildren = toc.getNumChildren();
    for (var i=0; i < numChildren; i++) {
      var itemInfo = {}
      var tocItem = toc.getChild(i).asParagraph();
      var tocItemAttrs = tocItem.getAttributes();
      var tocItemText = tocItem.getChild(0).asText();

      // Set itemInfo attributes for this TOC item, first from Paragraph
      itemInfo.text = tocItem.getText();                // Displayed text
      // ... then from child Text
      itemInfo.linkUrl= tocItemText.getLinkUrl();      // URL Link in document
      contents.push(itemInfo);
      
    }
  }

  // Return array of objects containing TOC info
  return contents;
}

function test_parseTOC() {
  var fileId = '--Doc-ID--';
  var array = parseTOC(DocumentApp.getActiveDocument().getId() );
  Logger.log(array)
}

The function test_parseTOC returns the following array:

[{linkUrl=#heading=h.nyq88bov1u8x, text=Google}, {text=Help, linkUrl=#heading=h.9lthewlyeqjd}]

Although the information is correct, the "=" is giving me trouble. When working with an array of objects I would expect it to be:

[{linkUrl: "#heading=h.nyq88bov1u8x", text: "Google"}, {text: "Help", linkUrl: "#heading:h.9lthewlyeqjd"}]

What I am trying to emulate can be outlined by this post here (Google Apps Script: how to copy array of objects to range?)

If I manually change the "=" to ":" and add quotation marks then the array works fine. Is there something with the original function I can change to produce a ":" instead of a "="? Or is there a way to modify the array of objects after the fact to replace the "=" with ":"? I could easily use concat to automatically add the quotation marks, but the "=" is out of my wheelhouse.

Thank you for any input on this

Update: It actually turns out that this code was working appropriately and I was receiving an error from a different function that was using the output of this one (i.e. I wrote .getSheets(0) not .getSheets()[0]. I will leave up the original post in case anyone needs a working example of how to extract out links from a TOC and along with the resources to write it to a google sheet
