You have requested a non-existent service "ds.ds_block_field_entity_context"

You need to clear the caches, e.g. drush cr
See 🐛 Error: Class "Drupal\ds\ContextProvider\DsBlockFieldEntityContext" not found Closed: works as designed as well.

I've run drush cr and drush updb about 1000 times trying to fix this. That is not the issue.

Are you able to check if ds.services.yml still contains 'ds.ds_block_field_entity_context' ? If so, than something went wrong with the update in that installation, as the corresponding class 'DsBlockFieldEntityContext' has been removed. Those lines shouldn't be there in the services file.

I found that @ds.ds_block_field_entity_context:block_content was being referenced in a view config file that wasn't even really being used, but it caused my whole site to lock up. Not sure if that's a bug onto itself, but it seemed to be rather unforgiving as far an error.

In the end the reason I wasn't finding 'ds.ds_block_field_entity_context' when I searched my codebase was because the /config files were in my gitignore and I didn't really Sublime Text was excluding search results based on my gitignore. Found it using the macOS Spotlight search instead. Thanks for the help!

Hmm, interesting that this is stored somewhere, didn't expect that. But good to know!

Hi, I also find the same error, please see:

The website encountered an unexpected error. Try again later.

Background:
I was migrating the website from Drupal 9 to 10.
And the previous DS module was 8.x-3.15.

I have DS fields in the project, like the config (config/sync/ds.field.buszmegallo_helyszinekkel.yml):

id: buszmegallo_helyszinekkel
label: 'Bus stops'
ui_limit: 'bus_line|*'
type: block
type_label: 'Block field'
entities:
  taxonomy_term: taxonomy_term
properties:
  block: 'views_block:buszmegallok_es_helyszinek-block_1'
  use_block_title: false
  add_block_wrappers: false
  config:
    id: 'views_block:buszmegallok_es_helyszinek-block_1'
    label: ''
    label_display: visible
    provider: views
    context_mapping:
      field_bus_stop_line_target_id: '@ds.ds_block_field_entity_context:taxonomy_term'
    views_label: ''
    items_per_page: none

Of course, this may not be relevant.

I use the latest stable version, 8.x-3.19.

Do you have any idea?

I faced the same issue as #7. In my case I had custom DS block fields that were holding views blocks. These views all had contextual filters.

In D9, such DS fields were created with @ds.ds_block_field_entity_context:[entity] in their context mapping. As per #4, this context was removed from DS, so a manual resave was necessary on these DS fields' Configure block form (located at /admin/structure/ds/fields/manage_block/[ds_field_name]/block_config).

To summarize, the following steps fixed the exception for me:

1. Search for the string "ds_block_field_entity_context" among the site's config files: grep -nri ds_block_field_entity_context ./config/
2. For each ds.field.[ds_field_name].yml in the grep result, submit the settings form at /admin/structure/ds/fields/manage_block/[ds_field_name]/block_config

Diff after executing above steps and a fresh config export:

 context_mapping:
-      nid: '@ds.ds_block_field_entity_context:node'
+      nid: '@node.node_route_context:node'
