Configuration core.entity_view_display.paragraph.nested.default depends on the field.field.paragraph.nested.layout_builder__layout configuration that will not exist after import.

This is saying it thinks you have layout builder for that view mode.
If you don't, edit the yml file and remove the dependency on that field and try again.
Drastic but safe to do if you know you don't use layout builder on that view mode.

Excellent idea! But, how? There is no reference in the yml to paragraph, nested, layout or builder or configuration.

I've looked at his code again and again and again, and I can't figure out how it even *knows* about layout builder when there doesn't appear to be anything in the yml file that references it!

I tried removing the group and user module dependencies. No change. I even removed the language contexts. Nothing.

Layout builder *is* on both the source and destination sites, and I did find this:

Since the base table is groups_field_data, perhaps this has something to do with it? But, the nested paragraph is not associated with this view at all. Arrrrrggghhhh!!!!

Oh yes, I'm trying to import it as a view. Should I try view mode?

Relating this to this issue: https://www.drupal.org/project/drupal/issues/3335483 ✨ configuration override on single item imports Closed: works as designed

If this sort of problem can't be solved logically, how about an option to override blocking of configurations which the import program incorrectly identifies as missing?

So what has happened here is at some point the system you're trying to import into has gotten itself into a state where the configuration dependencies cannot be reconciled. Moving isolated pieces of content from one site to another isn't recommended, instead we expect you to sync a complete config set. However it sounds like you've started on this process, so we can try to help you reconcile it.

It sounds like the default view mode for the nested paragraph type thinks it depends on layout builder, but it doesn't. Your best bet is to navigate to the 'manage display' tab for the nested paragraph type and save it, hopefully that is enough to fix the dependency issue. If that does fix it, then happy days.

However, if that doesn't work, I'd suggest a complete export of your configuration on the site where you're trying to import, then find the file named core.entity_view_display.paragraph.nested.default.yml.

Inside that file, it has a dependency on field.field.paragraph.nested.layout_builder__layout, remove that line and then try a complete import. Because you've been doing partial syncs, you may find there is another error, and it will likely be a process of working through them one by one. Feel free to keep posting updates here and we'll try to help.

This absolutely worked! I just saved the existing "Manage display" config on the destination site and the import went through with no issues.

Actually, there were three config errors on import. These were the other two:

Configuration block.block.drupal8_w3css_subtheme_custombooknavigation depends on the Custom Book Block module that will not be installed after import.
Configuration block.block.somebody_custombooknavigation depends on the Custom Book Block module that will not be installed after import.

This made sense because the Custom Book Block module was installed but not enabled on the destination site. Enabling it solved those two issues. I was stymied by the fact that the layout builder configurations were exactly the same on the source and destination sites.

This helps tremendously moving forward. Thank you so much!
