I am developing a package that has an artifact set up as `lazy` as shown in the following `Project.toml` and so requires `using LazyArtifacts,` which is part of `stdlib.` However, `resolve()` complains that it has `no known versions.` Any help on what I’m missing gratefully received.

Where did you find that UUID? It should be

```toml
LazyArtifacts = "4af54fe1-eca0-43a8-85a7-787d91b784e3"

```

> <https://github.com/JuliaRegistries/General/blob/2a2cd3e8e55a2debf3123954ed9a9c57abd8e543/L/LazyArtifacts/Package.toml#L2>

Did you use any GenAI tool by any chance? I’ve seen them making up UUIDs several times.

Guilty. I’ll know to check the Registry in the future.

Or actually use the package manager to create the project file 🙂
