Route group and layout at top level prevents root index page from being rendered

[octopicorn]

With the following file structure (file based routing):

src/routes/
  (landing-pages)/  <- this is a route group which will not appear in the url path
      _layout/
          index.tsx // <- this is the home page with layout applied
          about.tsx
          contact.tsx
      _layout.tsx // <- this is the layout file

Expected result:
Home page is rendered with the layout applied.

Actual result:
No home page is rendered at all.

If I remove the (landing-pages) route group, rendering works again as expected. There seems to be something about the route group at top level that prevents the route '/' from rendering _layout/index.tsx wrapped by _layout.tsx.

I've reproduced this in a CodePen based off of the Basic example in the docs.

Is layout supposed to work in combination with route groups? Or is it an either/or set of features?

This is a real use case. I want Home and several other pages to share a "top level" layout, let's say a left nav and header. Then I want a set of subpages to share a completely different layout (not inheriting from top level layout at all), like a project workspace with tabs.

I thought route groups might offer me a way to separate these two groups of layout groups, but it seems like there is something about the root index page that doesn't fit this pattern.

looks like a bug in the generator. can you please create an issue with a minimal complete example (fork one of the existing examples on Stackblitz)?

Also trying to have root index nested in a layout to completely separate it from auth & other layouts

Tried couple of ways

tree app/routes
app/routes
├── (auth)
│   └── login.tsx
├── (main)
│   ├── _layout
│   │   └── index.tsx
│   └── _layout.tsx
└── __root.tsx

tree app/routes
app/routes
├── (auth)
│   └── login.tsx
├── (main)
│   └── index.tsx
├── _(main).tsx
└── __root.tsx

tree app/routes
app/routes
├── (auth)
│   └── login.tsx
├── _main
│   └── index.tsx
├── _main.tsx
└── __root.tsx

Actually while writing this I got the 1. approach kinda working in Stackblitz tho navigating causes different errors https://stackblitz.com/edit/github-3ber8h locally I can't get it working at all

Also played around with the routeToken approach using the default and changing it to layout as suggested here #1102 (comment) tho still failing

Tried this one as it looks promising https://github.com/SeanCassiere/nv-rental-clone/blob/master/src/routes/_auth/(dashboard)/_index.tsx

with the following tsr settings

indexToken: "_index",
routeToken: "_route",

tho I get the following error when navigating to any route within _main where _index.tsx lives in my case. routeTree.gen looks good to me

this is just an exerpt the full trace is quite long

[schiller-manuel]

you cannot use a _ in the token as they will be interpreted as layouts

[CanRau]

removed token config and renamed to index.tsx still same error
