Drupal 8.x

Hi

I'm trying to display nearest stores to a certain location (Geolocation field) found on a node and I'm using this guide:

https://www.drupal.org/docs/contributed-modules/geolocation-field/how-to...

But for some reason I can find this

"5. Select the Entity ID Context Filter option and select the contextual filter you created above."

I've installed Drupal 8, I've created a PHP file to read a XML file and insert some items, but I'm getting this error.

Fatal error: Uncaught Error: Class 'Drupal\node\Entity\Node' not found in C:\xampp\htdocs\drupal8\migracion.php:12 Stack trace: #0 {main} thrown in C:\xampp\htdocs\drupal8\migracion.php on line 12

This is the code I am using.

I used migrate module to convert my site from Drupal 7 to Drupal 8.9.x. The content types and contents got migrated correctly. However when I try to create a view using a specific content type, I am unable to see the fields. Explaining the steps i followed:

Hi everyone, 

I have a content type "sale" with a field "date", and I would like to delete node automaticaly when date is more thant 7days after now.

Rules en Drupal 8, is a nightmare for me ! I tryed to make a custom module but it's not a success...

Do you have a solution for me ?

Thank you so much for your help !
