script to reduce images

I developed a script that basically takes answers sent from the forms to the sheets, copies them from tab1 to tab2 inside the sheets, but one of those answers is an image and I found that if the script has more than 1 million pixels, I tried to work around it this of diversifying forms but always gives some error, sometimes the script completes but does not fulfill its function.

script1:

function onFormSubmit(e) {
  // obter informações sobre a última linha inserida
  var sheet = SpreadsheetApp.getActiveSheet();
  var lastRow = sheet.getLastRow();
  var colB = sheet.getRange(lastRow, 2).getValue();
  var colC = sheet.getRange(lastRow, 3).getValue();

  // redimensionar a imagem, se necessário
  var blob;
  try {
    blob = UrlFetchApp.fetch(colC).getBlob();
    var size = blob.getBytes().length;
    if (size > 1000000) {
      blob = resizeImage(blob);
      var file = DriveApp.createFile(blob);
      colC = file.getUrl();
      file.setTrashed(true);
    }
  } catch (e) {
    Logger.log("Erro ao redimensionar imagem: " + e);
  }

  // inserir informações na planilha de evidências
  var evidencias = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("evidencias");
  evidencias.getRange("B7").setValue(colB);
  if (blob) {
    try {
      var image = evidencias.insertImage(blob, 2, 10, 8, 15);
      image.setHeight(240);
      image.setWidth(400);
    } catch (e) {
      Logger.log("Erro ao inserir imagem na planilha: " + e);
    }
  }
}

function resizeImage(blob) {
  var MAX_WIDTH = 800;
  var MAX_HEIGHT = 600;

  var image = ImgApp.open(blob);
  var width = image.getWidth();
  var height = image.getHeight();

  if (width > MAX_WIDTH || height > MAX_HEIGHT) {
    if (width / MAX_WIDTH > height / MAX_HEIGHT) {
      height = Math.round(height * MAX_WIDTH / width);
      width = MAX_WIDTH;
    } else {
      width = Math.round(width * MAX_HEIGHT / height);
      height = MAX_HEIGHT;
    }
    image = image.doResize(width, height);
  }

  return image.getAs("image/jpeg");
}

script2:

// Adicione o ID da pasta onde as imagens serão armazenadas
const PASTA_ID = "1FtfoTwaj2_8pQBF4WN8YY8RLi-cWz2rPrxX7poYU0LcsDmf6U532DEbLJJXxZSUdSACqxqYB";

function onFormSubmit(e) {
  var sheet = SpreadsheetApp.getActiveSheet();
  var lastRow = sheet.getLastRow();
  var colB = sheet.getRange(lastRow, 2).getValue();
  var colC = sheet.getRange(lastRow, 3).getValue();

  // redimensionar a imagem, se necessário
  var blob;
  try {
    var file = DriveApp.getFileById(colC);
    var thumbnailLink = file.getThumbnailLink();
    if (thumbnailLink != undefined) {
      var thumbnail = UrlFetchApp.fetch(thumbnailLink).getBlob();
      var image = ImgApp.open(thumbnail);
      image = image.doResize(500);
      blob = image.getAs("image/jpeg");
    } else {
      blob = file.getBlob();
    }
  } catch (e) {
    Logger.log("Erro ao redimensionar imagem: " + e);
  }

  // inserir informações na planilha de evidências
  var evidencias = SpreadsheetApp.getActiveSpreadsheet().getSheetByName("evidencias");
  evidencias.getRange("B7").setValue(colB);
  if (blob) {
    try {
      var image = evidencias.insertImage(blob, 2, 10, 8, 15);
      image.setHeight(240);
      image.setWidth(400);
    } catch (e) {
      Logger.log("Erro ao inserir imagem na planilha: " + e);
    }
  }
  Logger.log("Dados inseridos na planilha de evidências");
}

I expected that the script had taken the images from the drive and then had them reduced and attached to a range of merged cells (B11:H25) in the correct tab, however only the texts passed and the scripts failed in the part of the images.
