How to import to a subcollection

[gtlsgamr]

I am trying to export a top-level collection foo which exports just fine.
Next, I want to import this exported json into a second level collection, which is foo/baz.

I am getting the below error
Error: Value for argument "documentPath" must point to a document, but was "foo/baz/bar/bat/23/taz/1wda". Your path does not contain an even number of components.

Below is the command I am using to export
backfire export ./testdata --config config --paths foo --debug

And to import

backfire import ./testdata.ndjson --config config --gcpProject project --debug

FYI, in the json I am editing all the paths that begin with foo with foo/baz

Hi @gtlsgamr, the error should be fairly self explanatory, and it comes from the Firebase SDK. Please take a look at the Cloud Firestore Data model to understand how documents and collections work.

By changing foo to foo/baz, you've turned your paths, which would have been originally pointing to documents, to be pointing to a collection.

For example, users/john would have pointed to a document with the ID john in the collection users. You've now changed the path to users/baz/john, which is now pointing to a subcollection called john under the document baz. You cannot import a document to to a collection path.

If you want to change the nesting level of your documents, you'll need to add an even number of segments.

Closing this as it's not an issue with the package, but feel free to reply if you need further assistance!
