Issues with beans in the migration (some nodes don't migrate, some migrate old revisions)

I am trying to do a migration from Drupal 7 to Drupal 9. Most seems to migrate okay but I noticed the following problems:

• I am missing some nodes
• Some nodes migrated only old revisions of the node (IE: In the live site a node has 8 revisions, and the migration only migrated the first 2, leaving the most recent of the 2 as the live content, which is a review from 2015. The most recent review in the site is from 2021)

The issue probably comes from one of those notices, I am just not too sure how to fix it or debug them:

The "bean" entity type does not exist. (/app/web/core/lib/Drupal/Core/Entity/EntityTypeManager.php:143)
[notice] Cannot change the field type for an existing field storage. The field storage node.field_thumbnail has the type entity_reference. (/app/web/core/modules/field/src/Entity/FieldStorageConfig.php:375)

Any tips to migrate beans? I tried using the module "bean migrate" but then those notices turn in to:

 [notice] Upgrading bean:homepage_information_block_base

I am fairly familiar with Drupal, just not so much with Migrations, so any general tips to help me debug/fix would be appreciated
