Upgrading from 2.0 to 2.1 removes DER module without uninstalling it first

I confirm the issue. drush updb is failing after the upgrade to 2.1 : The "field_item:dynamic_entity_reference" plugin does not exist.

The same is also happen on a move from 2.0.0 to 2.0.2. Looking at the original ticket for this issue there was someone who had the same issue https://www.drupal.org/project/linkchecker/issues/3375553#comment-15767610 📌 Remove dependency of Dynamic Entity Reference (DER) Active

Basically the "workaround" is to composer require 'drupal/dynamic_entity_reference:^3.2' prior to trying to run the database update. I've confirmed this works, though it doesn't resolve the issue of the site breaking on update. I'm bumping up the priority to Major and moving the Version to 2.0.2 to reflect the issue being a part of recommended releases.

I am also experiencing this issue. The workaround to include dynamic_entity_reference like we're all doing works but worth noting.

Yes please manually perform the workaround. I'm not sure of a better way at this time that would work for everyone as some folks may still need dynamic_entity_reference.

It's a catch 22 here.

Then have a celebration for no longer needing dynamic_entity_reference! A significant simplification!

Best thing would be to pin this workaround as a note on all 2.1.x and 3.0.x release notes and add it to the README.md.

Please create a merge request with an update to the README.md

Setting as a bug report since a hook_update could easily deal with the second upgrade related issue which is to clear out and re-analyze the links.

isolating this back to the 2.0.x -> 2.1.x upgrade path
