Drupal 8.x

I´m trying to group two fields in a table view but the following message appears : 

Competicion (one of the two fields): <!-- THEME DEBUG --> <!-- THEME HOOK: 'views_view_field' --> <!-- BEGIN OUTPUT from 'core/themes/stable/templates/views/views-view-field.html.twig' --> <a href="/node/443" hreflang="es">Trofeo Rectora</a> <!-- END OUTPUT from 'core/themes/stable/templates/views/views-view-field.html.twig' -->

and it doesnt works! Somebody know something about this?

Thanks all!

Sometimes, during development, it happened that the views gave a json problem.
Once, in an editable view, but I was able to understand that the problem was that it must not have the cache.
Other times, without understanding why, this happened in normal views by saving settings or simply adding fields to an already existing view. In these cases I solved it by going back to the previous backup.

But the reality is that I can't understand "what" should be avoided (apart from the conflictiong modules) in order not to get these problems.

Hi all, 

I'm trying to fill some fields of my Media Type "Image" using the information obtained from the uploaded image. I explain what i did for now:

I have a Media Type "Image" with 4 fields:

- Title

- Description

- Image with Alt text

- Copyright

I create a new media "Image" and I upload a image. As soon as the image has been uploaded I want to fill Name, Description, Alt text and Copyright from the data of the image.

I want to figure out a way to display the contents of a basic page node on my user profile tab menu.

I found the way using views to generate the tab, and the path, and made a basic page test like I said, and it worked like I wanted making a "My Work" tab at /user/*/my-work.
