Module development and code questions

I'm having trouble doing a redirect to a named route. Here is my routing.yml and controller code:

Hi team

I'm migrating our content types from drupal 7 to drupal 8,
I've been creating our content types and their fields manually in drupal 8, but i would like to know if there is an option or a module to export them, I just want to export the fields for those content types not the nodes.

Could you please help me?

Regards

Mario

I have create a feed that takes content from a csv containing several columns of data that includes Title, a published date, website, email address, some taxonomy fields like news type and subject tags  and body field.  The body contains html data that has been exported from Drupal 7 site.  

The feed is set format Full HTML

When running the feed i get an error message and the content is not created.

This is the top of the error message

An AJAX HTTP error occurred.

HTTP Result Code: 500

Debugging information follows.

What's the proper way to set the default value? This happens to be a checkboxes field. The value assigned must be an array.

function hook_form_node_<content_type>_edit_form_alter(&$form, FormStateInterface $form_state, $form_id)
{
...

$form['field_offices']['widget']['#default_value'] = ?

...
}
