entity_lookup for user entity type I'm trying to link a field in my spreadsheet file to a user that is previously created with a migration from the same spreadsheet. The Backup column consists of multiple names divided by the backward slash (Firstname Lastname/Firstname Lastname)
migrate_plus.migration.profiles.yml:
process:
  field_backup:
    -
      plugin: explode
      delimiter: '/'
      source: 'Backup'
    -
      plugin: entity_lookup
      value_key: name
      ignore_case: true
      entity_type: user
      bundle_key: uid
      bundle: people

migrate_plus.migration.users.yml:
process:
    name:
      plugin: concat
      source:
        - 'Firstname'
        - 'Lastname'
      delimiter: ' '

The backup field is just skipped when migrating the profiles. The only error I'm getting is when i go to a profile page and check the log messages.

User error: &quot;attributes&quot; is an invalid render array key in

Can you not use entity_lookup for users or am I doing something wrong in my configuration?
Any help would be much appreciated
If your entity_lookup is searching Users then the bundle, I think, should also be user since there is no people bundle.
