why is my xhr response {"success":false,"token":null} [closed]

I haven't used this application/website in a couple of months. I tired using it today and it's failing. The login page gets a token and passes it to the main processing .html that calls common.js. When checking the dev tools, the function POSTs, the Authorization: in Networks/Headers looks correct, but the response is "success":false,"token":null}".

I'm about to tear my hair out, as it must be something simple.

It's hosted by GoDaddy and we had to upgrade from PHP7.4 to 8.4. Could that cause the issue?

If I use an invalid user name or password, everything works as expected. If I enter a valid name and password, I get this failure.

Any thoughts?

Here's code, where I've removed all the processing and am only displaying messages on the console:

function getDate() { var token = sessionStorage.getItem('token'); console.log("common.js: getDate called, token =", token); if (!token) { console.warn("common.js: No token found!"); return; } var settings = { type: 'POST', url: app_url + '/v1/date-list', beforeSend: function(xhr) { xhr.setRequestHeader('Authorization', 'Bearer ' + token); xhr.setRequestHeader('Content-Type', 'application/json'); console.log("common.js: Authorization and Content-Type headers set"); }, data: JSON.stringify({}), // send empty JSON payload dataType: 'json', success: function(data) { console.log("common.js: Date-list response:", data); }, error: function(jqXHR, textStatus, errorThrown) { console.error("common.js: AJAX error", textStatus, errorThrown); console.log("common.js: Full jqXHR object:", jqXHR); }, complete: function(jqXHR, textStatus) { console.log("common.js: AJAX request complete, status:", textStatus); } }; console.log("common.js: var settings, token =", token); console.log("common.js: var settings, headers =", Headers); console.log("common.js: AJAX settings prepared:", settings); $.ajax(settings); }

Here's the console messages:
