It's pretty confusing that this error message will contain the singleton type name: "The [enabled] parameter can't be updated for the object mapping [_doc]." I think we should address this in a separate, more general change to not pass in the type as the root object mapper's name.

I'll double check with someone from the distributed team that this change is okay.

@original-brownbear would you be up for taking a look? I saw that you made several changes in this area recently.

I think this is fine. This line seems unnecessary and makes the test behave less like a real restore as far as I can see anyway (just restoring the meta from the repo in a real restore).
=> LGTM :)

Thanks @original-brownbear ! It also seemed strange to me, that we would add the original mappings as part of restoring a source-only snapshot.

Although it could be considered breaking, I plan to backport this to 7.8. This matches how we handled #33933, which prevented changing |

In #33933 we disallowed changing the
enabledparameter in object mappings.However, the fix didn't cover the root object mapper. This PR adjusts the change
to also include the root mapper and clarifies the error message.
