Services with $path but not $className turn into folders

[vocksel]

I have partitions to ReplicatedStorage, ServerScriptService, and StarterPlayerScripts. I removed the $className field from all three. When running rojo build, ReplicatedStorage syncs normally, however ServerScriptService and StarterPlayerScripts both create new Folders instead of placing instances in the actual service.

I'm not sure if this one is a bug or something we should document. I'm going to make a couple assumptions about how your project is structured; let me know if I'm wrong here!

Rojo always requires $className if it cannot intuit what the ClassName of an instance should be. One way that can happen is if your project node has $path defined. If $path is pointing to a folder, then the ClassName of the resulting instance will likely be Folder!

You should have a couple options to fix this:

1. Keep using $className when you're also using $path
2. Create init.meta.json files in the affected folders
3. Move any project nodes that require $path one level down. Instead of specifying all of ServerScriptService via $path, just specify some subset of it.

You're exactly correct. Most of my partitions look like this:

"ServerScriptService": {
	"$className": "ServerScriptService",
	"$path": "src/server"
},

So when $className is removed, it's assuming Folder. The reason this didn't happen with ReplicatedStorage is because every project node is nested within a subfolder, just as you mentioned.

Definitely doesn't sound like a bug then, just something that could probably do with documentation

After @nezuo's comment in #13, I'm wondering if this is something we should actually change instead of document. It's not likely that you want a Folder when you're in the same spot in the DOM as a service would be. We can probably loosen the logic here to overwrite Folder, or maybe overwrite Folder in certain circumstances?

I'm having the exact same issue, except this time Rojo crashes with

[ERROR] Rojo crashed!
[ERROR] This is probably a Rojo bug.
[ERROR]
[ERROR] Please consider filing an issue: https://github.com/rojo-rbx/rojo/issues
[ERROR]
[ERROR] Details: If $className and $path are specified, $path must yield an instance of class Folder

when trying to set $className to the correct service class name.

EDIT: Rojo 6.0.2 on Windows 10 Insider Preview 21364.1 (co_release)

This is fixed up in master! We have much better error messages, and now this case is handled as expected.

I'm currently have the same issue.
