Nondeterministic error in CI saying there is no writable folder in the load path

[gdalle]

Hi there,
I recently encountered a weird error in the CI of a package calling DataDeps.jl:

┌ Error: No writable path exists to save the data. Make sure there exists as writable path in your DataDeps Load Path.
│ See https://www.oxinabox.net/DataDeps.jl/stable/z10-for-end-users/#The-Load-Path-1
│ The current load path contains:
│   cands =
│    8-element Vector{String}:

│     "/opt/hostedtoolcache/julia/1.10.0/x64/local/share/julia/datadeps"

│     "/usr/local/share/datadeps"

Benchmarks: Error During Test at /home/runner/work/MultiAgentPathFinding.jl/MultiAgentPathFinding.jl/test/runtests.jl:22
  Got exception outside of a @test
  LoadError: DataDeps.NoValidPathError("No writable path exists to save the data.")

Here's the CI log. The weird thing about it is:

• this was the first time this ever happened to me (in this package or others)
• I resolved it by re-running CI (the last commit in this PR fixed it by changing an unrelated typo)

Any idea what this could be?

That's weird.
It either means no directory on inm the listed load path exists,
or if they existed then they had read-only permissions.

I would guess, some kinda transient but with the CI runner, maybe it initialized wrong some how.

I wouldn't worry about it unless it reoccurs

It just happened again ^^

I am hopeful that this will have been fixed by #167

This is likely due to the cache action. Yeah that PR should fix it I guess

closing this, reopen if it reoccurs
