Hi all — '’m hitting a puzzling failure building docs on Julia 1.12 where stdlib JLLs fail to load during precompilation. It happens in GitLab CI. Here’s the error

```julia-auto
  julia --project=docs -e 'using Pkg; Pkg.develop(PackageSpec(path=pwd()));
  Pkg.instantiate(); include("docs/make.jl")'

  Error (abridged)
  Precompiling packages...
  ✗ LibSSH2_jll
  ✗ LibGit2_jll
  ✗ LibCURL_jll
  ✗ LibGit2
  ✗ LibCURL
  ✗ Downloads
  Info Given Pkg was explicitly requested, output will be shown live
  ERROR: LoadError: ArgumentError: Package OpenSSL_jll [458c3c95-2e84-50aa-8efc-
  19380b2a3a95] is required but does not seem to be installed:

```

Here is the [CI file](https://gitlab.com/newptcai/llmaccess.jl/-/blob/main/.gitlab-ci.yml?ref_type=heads). You can see the [full GitLab job log](https://gitlab.com/newptcai/llmaccess.jl/-/jobs/11893823994). It not sure what went wrong by looking at it. Any suggestions?

Probably because your [`docs/Manifest.toml` is for 1.11](https://gitlab.com/newptcai/llmaccess.jl/-/blob/main/docs/Manifest.toml?ref_type=heads#L3), but you’re using Julia 1.12? Updating (or removing) the manifest might fix it.
