Describe the Bug

I have the following folder structure:

src/
└─ content/
   ├─ blog/
   │   └─ my-article/
   │     ├─ my-article.md
   │     └─ _some-data.json
   └─ config.ts

(I refer to _some-data.json from my layout through some arcane way that does not matter in this context.)

In dev, this works, _some-data.json is ignored, as files prefixed with underscores should be. In build however, _some-data.json is being passed through the Zod schema as if it was a file that needs to respect the blog schema. I would like for this file to be completely ignored, like it is in build.

I believe this is a regression from 2.5. This used to work with 2.4.

Yes, 2.5 added data collections. Before that, JSON files were never processed, underscore or not

Hi @bholmesdev, I just updated to Astro 2.5.6 and seem to be having a similar, but slightly different issue.

I have the following folder structure:

src/
└─ content/
   ├─ blog/
   │   └─ my-article/
   │     ├─ my-article.md
   |     ├─ _my-data-directory/
   │       └─ some-data.json
   └─ config.ts

My json data (some-data.json) is NOT prefixed with an underscore, however it is in a directory (_my-data-directory/) that is prefixed with an underscore.

I am getting the same issue where the build fails because it does not match the collection schema. May I ask if this is the intended behavior and it is required for json files to be always prefixed with an underscore even if it's already in a directory prefixed with an underscore?

Ah, definitely an oversight. I see what we missed @tonydangblog. Reopening to make that fix

This issue is back since 2.7.1. Highly likely it's this commit: 478cd9d
