Drupal 8.x

I have the following code for a dynamic route:

route_callbacks:
  - '\Drupal\epensions\Routing\ClientSelector::routes'

The router class is as follows:

I have upgraded the Drupal core 8.5.3 but I am unable to login with Github when we click github icon it is showing the errors.

We have a webinar page content type. A couple of fields have content for when the webinar is upcoming. Then it automatically unpublishes on the  day of the webinar. After that, we modify a couple fields, and the content, then turn it back on as an archived webinar.

example, before the webinar the button text says "register now". After, we change the button text to "watch now"

I'm trying to create an RSS feed from our Events calendar. WHen I'm creating the view, under FORMAT, I choose:

Format: RSS Feed

Show: Fields

The fields I want mapped to description are event date and location. I tried creating a fieldset of those two elements, but when I preview the feed it just says

<description>[field_event_date_1|field_address_1]</description>

What should I be doing?

Here are the steps .

1. Load the page in browser mydomain.com/eu/custom-page
2. Click on contextual edit button which opens the drupal editing interface.
3. Make updates on custom-page node.
4. Save and Publish the changes.
5. Page is redirected to mydomain.com/node/xyz instead of mydomain.com/eu/custom-page . Although the updates are saved.

Can somebody suggest what should I do to fix this ?
