Problem with empty input in emailjs

Hello, everyone. I have a problem. When I try to send an email form on netlify or netlify dev this goes empty.
On my local server this working perfectly.
This is my HTML:

          <form id="mailer" method="post" class="contact-form lg-6" action="contact" >
            <div class="form-group">
              <div class="input-group input-group-lg mb-3">
                <input name="Full name" type="text" id="contact-name" class="form-control" placeholder="Full name"aria-label="Name" aria-describedby="inputGroup-sizing-lg"  value="" required/>
              </div>
  
              <div class="input-group input-group-lg mb-3">
                <input name="Company" type="text" id="contact-company" class="form-control" placeholder="Company" aria-label="Company" aria-describedby="inputGroup-sizing-lg" value="" required/>
              </div>

              <div class="input-group input-group-lg mb-3">
                <input name="Email" type="email" id="contact-email" class="form-control" placeholder="Email" aria-label="Email" aria-describedby="inputGroup-sizing-lg" value="" required/>
              </div>

              <div class="input-group mb-3">
                <textarea name="textarea" id="contact-textarea" class="form-control" aria-label="With textarea" value="" required></textarea>
              </div>
              <button href="#home" type="submit" class="btn btn-primary submit">Send</button>
            </div>
          </form>

and my JS:

  function handleChange(e) {
    value = e.target.value;
  }

  nameInput.addEventListener("blur", handleChange);
  companyInput.addEventListener("blur", handleChange);
  emailInput.addEventListener("blur", handleChange);
  textareaInput.addEventListener("blur", handleChange);

  let templateParams = {
    from_name: "Contact Mailer",
    to_name: `${toEmail}`,
    fullName: `${nameInput.value}`,
    company: `${companyInput.value}`,
    email: `${emailInput.value}`,
    msg: `${textareaInput.value}`,
  };

  form.addEventListener("submit", function (e) {
    e.preventDefault();

    emailjs.send(serviceID, templateID, templateParams).then(
      function (response) {
        console.log("SUCCESS!", response.status, response.text);
      },
      function (error) {
        console.log("FAILED...", error);
      }
    );
    nameInput.value = "";
    companyInput.value = "";
    emailInput.value = "";
    textareaInput.value = "";
  });

I don’t know where is the problem. Please, help me.

Hey @kamilsulgut,

What error are you getting? Could you please share a site name?

Also, are you using: GitHub - emailjs-com/emailjs-sdk: EmailJS helps sending emails using client side technologies only. No server is required.?
