Steps to reproduce

  1. Go to /admin/config/system/mailer and add a new Policy, After selecting Type and adding Sub-Type it will redirect to Policy edit form.
  2. Select any element and press "Add Element".
  3. Add element details and press Save on the form.

Proposed resolution

I guess that the #empty_value is causing that error since it is producing empty value for configs (but I am not sure, needs to be verified).

$form['add_actions']['add_select'] = [
  '#type' => 'select',
  '#options' => $options,
  '#empty_value' => '',
  '#empty_option' => $this->t('- Select element to add -'),
];

    It works for me and no one else has reported. Maybe it is related to something on your site? I suggest to test with creating policy for one of the Core modules.

    Hi Adam,
    I also tried with one of the core modules and it behaves the same

    I just completed a Drupal 10 upgrade and I'm getting this same error when I try to add a new element to an existing policy. It worked without problems during the entire development process, but now that I've pushed the upgrade to production it fails.

    Drupal\Component\Plugin\Exception\PluginNotFoundException: The "" plugin does not exist. Valid plugin IDs for Drupal\symfony_mailer\Processor\EmailAdjusterManager are: mailer_url_to_absolute, email_bcc, email_body, email_cc, mailer_default_headers, email_from, mailer_hooks, mailer_inline_css, email_plain, email_priority, email_reply_to, email_skip_sending, email_subject, email_theme, email_to, email_transport, mailer_wrap_and_convert in Drupal\Core\Plugin\DefaultPluginManager->doGetDefinition() (line 53 of /var/www/web/core/lib/Drupal/Component/Plugin/Discovery/DiscoveryTrait.php).

    I should add that this is a policy for email receipts in Drupal Commerce.

    The problem was competing form actions. There was $form['add_actions'] as type 'action' and then $form['actions'] as type 'action.
    The $name variable was always empty (attached screenshot) when clicking the Save button, hence the error in this issue.
    The solution was to make $form['add_actions'] a container within the existing $form['actions'].
    Patch added.

    Thanks. Drupal.org now uses requests instead of patches please.

    Thanks. For me the result is worse than before. Before the select and button were on the same line, and now they are one below the other - see screenshots attached.

    I believe that the buttons are no longer in the container because they still have $form['add_actions']. Instead it worked for me like this:

        $form['add_actions'] = [
      '#type' => 'container',
      '#weight' => -1,
      '#attributes' => ['class' => ['container-inline']],
    ];

    Please can you check if that still works for you, then update the MR?

    I can confirm the above in #13 works fine!
