Express Forms Not Sending Notification Emails

Question

Craft 3.3.0.1 Express Forms 1.0.4

I have an Express Forms set up. It submits and saves entries to the DB which can be viewed in the CP, however email notifications are not sent.

Sending a test email via settings > email works as expected as does a different Express Forms form, but this one does not and I am flummoxed.

when I check the Express forms log I see this:

Here is a simplified template of my form where you can see the notification email address are set to a field in the page entry or if that is empty default email addresses are used.

{# 
// set send email address from careers entry 
#}
{% set sendEmailAddress %}
  {# loop through emails from job entry page and set the form to send to those emails #}
  {% for email in entry.applicationEmails %}
    "{{ email.emailAddress }}"{% if not loop.last %},{% endif %}
  {% else %}
  {# if empty send to this address #}
    "[email protected]", "[email protected]"
  {% endfor %}
{% endset %}

{# this testing div outputs emails as expected #}
<div class="testing">
  {{ sendEmailAddress }}
</div><!-- /.testing -->


{% set form = craft.expressforms.form("jobapplication") %}


{# General Error Handling #}
{% if not form.valid %}
    <div class="alert alert-danger" role="alert">
        {{ "Error! Please review the form and try submitting again."|t }}
        {% if form.errors|length %}
            <ul>
                {% for error in form.errors %}
                    <li>{{ error|t }}</li>
                {% endfor %}
            </ul>
        {% endif %}
    </div>
{% endif %}


{{ form.openTag({
   return: '?success=1',
   dynamicNotifications: {
      to: [sendEmailAddress],
      template: "job-application.twig",
   }
}) }}

  {# 
    Various Fields here
  #}

  <button type="submit" data-application-submit class="btn btn-default" disabled>{{ "contact_submit"|t }}</button>

{{ form.closeTag }}

I've tried various approaches to using dynamic emails notifications but nothing seems to work.

My email notification template looks like this where {eMail} is the email field name in the form.

---
name: 'Job Application Email Notification Template'
description: 'submits job applications to reciever'
fromName: 'Strongco'
fromEmail: '$SYSTEM_EMAIL'
replyTo: '{eMail}'
cc: null
bcc: null
subject: 'Job Application: {positionAppliedFor}'
includeAttachments: true
---
<p>The following submission came in on {{ dateCreated|date('l, F j, Y \\a\\t g:ia') }}.</p>

<ul>
    {% for field in form.fields %}
        <li><strong>{{ field.label }}:</strong> {{ field.valueAsString }}</li>
    {% endfor %}
</ul>

Please advise.

I'm guessing if you update to the latest 3.x release of phpdotenv, the issue will resolve itself.

3.x added better support for environment variables running in multi-threaded environments. You can read some background info here: https://github.com/craftcms/cms/issues/3631

Note that you'll likely need to update how phpdotenv is loaded in your public index.php file. You can read the upgrade guide here: https://github.com/vlucas/phpdotenv/blob/master/UPGRADING.md
