Drupal 8.x

I have a csv file with user id, user name and role. I need to update fields user name and role to drupal users. The csv file have 12000 rows.
      

I created a module that read the csv file and update users, but when update some 3000-3500 users the execution stop without errors.
        
Whats is the best solution?

Good day,

I have a Drupal 8 project that needs to be retrieve/show the content from external website. 

Hi I have a csv like attached in the image.

When importing the content to corresponding content type, it shows an error like below.

Uncaught PHP Exception Drupal\\Core\\Entity\\EntityStorageException: "SQLSTATE[23000]: Integrity constraint violation: 1048 Column 'name' cannot be null: INSERT INTO {taxonomy_term_field_data}

I've just done a fresh install of Drupal-8.6.3 and no CSS will load in the default Bartik theme. I've tried changing themes and get an error that "permission is denied' although I'm using the initial admin account and haven't created any others. I've fixed the permissions on sites/default/files to be writable and this still doesn't help. Any idea what the problem could be? Thanks in advance..

I need to do something that I know is antithetical to Drupal 8:  insert inline JavaScript from a PHP function.  If time allowed, I would restructure the site to avoid this situation, but I don't have time.

I need to have a PHP associative array, encoded as JSON, to be available to the whole page within script tags.

The PHP object is created within function THEME_preprocess_views_view__VIEWNAME.  How can that associative array/JSON object be made available to JavaScript in the page?

Thank you in advance,

Mike
