Inline Images in Table Cells not Copying into New Document

Question

I have a program that copies the contents of various documents to a newly created document upon submission of a form. I am running into issues copying inline images embedded into tables.

When submitting the form, I get an email alert stating "Service unavailable: Documents" at the line "var dstImg = dstParagraph.insertInlineImage(l, srcImg.getBlob());" in the code below.

All of the Stack Overflow questions I have seen about this seem to stem from the fact that the user was not using Inline Images, rather Fixed Images instead. I have double-checked that my images are, in fact, inline. I do also have Google Docs and Drive API enabled.

Here is a link to the document that I am using:

https://docs.google.com/document/d/1WFEvhnW2FDtfBrDPiPXH1U09DD8mg6PA_Q6afciSLgU/edit?usp=sharing

Here is a link to a screenshot of what the generated document looks like when I receive the error message:

https://drive.google.com/file/d/1x36HFEAxiPWFOjLxLqkgDQYDnr0Fftem/view?usp=sharing

Here is a link to the form that is attached to this program: https://docs.google.com/forms/d/e/1FAIpQLSdNu3nTQF8s5ScYCLXLd1y0Ji3VKUMKtYIfa4-dIlZptRJ5wQ/viewform?usp=sharing

I realize that this is not a new issue, I have already looked at the following sources for help:

Google Apps Script - appendParagraph with image

Images disappear when nested inside a table and appended to a new document. Bug or did I miss something?

Here is the relevant code:

function CreateDocumentInFolder(e) {

 var formResponse = e.response;
 var itemResponses = formResponse.getItemResponses();
 var question_twelve_answer = itemResponses[12].getResponse();

 var page_number_template = DriveApp.getFileById('10HNrpwxkZsO7ulr8b61pvB6fnclLKMDbNUWI0Nw9Y9g')
 var student_lp = page_number_template.makeCopy( DriveApp.getFolderById('1a5k6yBqcQUL-g21oiCj3_wK9Njn-xML1'))

 var main_file_ID = student_lp.getId()
 var doc = DocumentApp.openById(main_file_ID)
 var body = DocumentApp.openById(main_file_ID).getBody();
 var otherBody12 = DocumentApp.openById('1WFEvhnW2FDtfBrDPiPXH1U09DD8mg6PA_Q6afciSLgU').getBody();

 if (question_twelve_answer != 'm<12') {
    var totalElements = otherBody12.getNumChildren();
      for( var j = 0; j < totalElements; ++j ) {
        console.log(j);
        var element = otherBody12.getChild(j).copy();
        var type = element.getType();

        else
          throw new Error("Unknown element type: "+type);

              var dstParagraph = dstTable.getCell(i, j).getChild(k).asParagraph();
              dstParagraph.getChild(l).asInlineImage().removeFromParent();
              // Issue is the line below!
              var dstImg = dstParagraph.insertInlineImage(l, srcImg.getBlob());
              dstImg.setWidth(srcImg.getWidth());
              dstImg.setHeight(srcImg.getHeight());
            }
          }
        }
      }
    }
  }
