On the homepage of my Flask application, I have an HTML table whose last column values can be text which can be schematized as follows:

I am now trying to use Javascript to convert all the "Edit Issue" values in the HTML table by an href link that would allow me once I click on this link to access another HTML page. For doing this, I loop every row in the HTML table and put HTML link inside cell. Unfortunately, when I run the code below, I get a source map error:

Please find below my JS code:

function convert_cellTable(){
let table=document.getElementsByTagName("table").value;
let row, rows = table.rows;
let cell, cells;

// For each row in the table
for (var i=0, iLen=rows.length; i<iLen; i++) {
  row = rows[i];
  cells = row.cells;

// Identify in each cell if the text content equal to "Edit Issue"
for (var j=0, jLen=cells.length; j<jLen; j++) {
  cell = cells[j];
  let TextToConvert = "Edit Issue"
  if (cells[j].textContent == TextToConvert) {
      // cell text is replaced by an HTML link
      cell[j].innerHTML = "<a href='updateform.html'>Edit Issue</a>";
  }
 }
 }
}  

Could you please provide me guidelines to correct the code above. Thanks
