[ickbinhier]

Tagged form type extension must have the extended type configured using the extended_type/extended-type attribute, none was configured for the "snowcap_im.form_extension" service.

this problem make a exception under symfony 3.1 and 3.2:

Script Sensio\Bundle\DistributionBundle\Composer\ScriptHandler::clearCache handling the post-update-cmd event terminated with an exception

in the changelog from symfony find this:

• The alias option of the form.type_extension tag is deprecated in favor of
  the extended_type/extended-type option.

  Before:

  <service id="app.type_extension" class="Vendor\Form\Extension\MyTypeExtension">
      <tag name="form.type_extension" alias="text" />
  </service>

  After:

  <service id="app.type_extension" class="Vendor\Form\Extension\MyTypeExtension">
      <tag name="form.type_extension" extended-type="Symfony\Component\Form\Extension\Core\Type\TextType" />
  </service>

i have in the moment th following 2 in file Resources/config/services.yml line 46 lines remove...

        tags:
            -  { name: form.type_extension, alias: snowcap_core_image }

But this is definitely not a solution.
