I have a form in a website that goes to a node.js backend, and in the form there’s two date selectors. When trying to pick a date I can’t get any results other than two arbitrary dates, which are Feb 1st 2024 and Oct 1st 2024.

I am not sure if I am missing something obvious or what is causing this bug.

What should I be doing different?/How can I get the date inputs to give the correct date?

HTML:

<div class="container parse">
    <form action="/parse" method="post">
        <select name="location" id="location" required>
            <option value="none" selected disabled hidden>Institución</option>
            <option value="1"> Arcoiris EP </option>
            <option value="1"> Albores ES </option>
        </select>
        <input type="date" name="startDate" id="startDate" required>
        <input type="date" name="endDate" id="endDate" required>
        <select name="employee" id="employee">
            <option value="none" selected disabled hidden>Empleado</option>
            <option value="none" >Todos</option>
            <!--list of employees from js array-->
          </select>
        <button class="btn"
           <!--htmx post req-->
        > Buscar </button>
    </form>
</div>

and the post request looks like:

app.post('/parse', (req, res) => {

params = {
    location: req.body.location,
    employee: req.body.employee,
    startDate: turnToDate(req.body.startDate),
    endDate: turnToDate(req.body.endDate),
};

console.log(`The parameters to search for are:
            start date: ${params.startDate} end date: ${params.endDate}
            for employee: ${params.employee}`) //***
const displayTable = mdb.parseMainTable(parseTable,
    params.startDate, params.endDate, params.employee);
const stringifiedHTML = createHTML(displayTable);
res.send(stringifiedHTML); 


//parseMainTable function from mdb module:

const parseMainTable = (parseTable, startDate, endDate, employee) => {
    let employeeFilteredTable = [];
    let displayTable = [];

    if (employee != 'none') {
        employee = Number(employee);
        employeeFilteredTable = parseTable.filter((el) => (el.id == employee));
    } else {
        employeeFilteredTable = parseTable
    };

    displayTable = employeeFilteredTable.filter((el) => (
        el.timestamp >= startDate 
        &&
        el.timestamp <= endDate
    ));

    return displayTable;
};

*** always logs “The parameters to search for are:
start date: Thu Feb 01 2024 00:00:00 GMT-0300 (Brasilia Standard Time) end date: Tue Oct 01 2024 00:00:00 GMT-0300 (Brasilia Standard Time)
for employee: none” or
The parameters to search for are:
start date: Tue Oct 01 2024 00:00:00 GMT-0300 (Brasilia Standard Time) end date: Tue Oct 01 2024 00:00:00 GMT-0300 (Brasilia Standard Time)
for employee: none

The list therefore ends up containing items in this arbitrary date range and nowhere else.
