Panic when creating new content _index.md then index.md

[irkode]

edit: added generated files

---

Hugo crashed when I accidently executed a rather strange sequence of new content commands:

I consider that as an edge case - but message itself states it as bug

I accidently [^1] tried to create *index.md files in the following order (one without underscore)

1. _index.md
2. index.md

Hugo crashed with: panic: [BUG] no Page found for "C:\_my\test\content\index.md"

Steps to reproduce: on Windows 10

PS C:_my> hugo version

hugo v0.123.7-312735366b20d64bd61bff8627f593749f86c964+extended windows/amd64 BuildDate=2024-03-01T16:16:06Z VendorInfo=gohugoio

Summary...

hugo new site foo
cd foo
hugo new _index.md
hugo new index.md

This was not a problem with v0.122.0. Fails with v0.123.0 and later.

I have something that might be related to this issue on hugo v0.125.4+extended linux/amd64 BuildDate=unknown VendorInfo=nixpkgs.

In my issue - when there is index.md - hugo doesn't generate content for any subfolders. E.g. if there is content/myFolder/post.md it will not generate in public

@ca5ua1 If you have a directory with descendant pages it is a branch bundle, and you must use an _index.md file instead of an index.md file. See documentation.

@jmooring ah, I see. That's confusing. Thanks for pointing that out
