Hi ! I added this JS code under assets/grants/grants.js. but it isn’t running in production. It works in development mode. I appreciate any help. Thanks.

const element = document.getElementById('select_tenant');
element.onchange = () => {
  const selector = document.getElementById('select_tenant');
  const tenantId = selector.options[selector.selectedIndex].value;
  const apiUrl = `/api/tenants/${tenantId}/apps`;
  fetch(apiUrl)
    .then(response => {
      return response.json();
    })
    .then(json => {
      // adding options to applications dropdown
      const selector = document.getElementById('app_select');
      while (selector.firstChild) selector.removeChild(selector.firstChild);
      json.data.forEach(app => {
        const option = document.createElement('option');
        option.text = app.name;
        option.value = app.id;
        selector.add(option);
      });
    });
};

Maybe a cache issue ? This is part of the Dockerfile
