I Julia, why is filter(isdir, readdir("data/") empty when readdir("data/") shows a dir?

I'm having some issues using a isdir filter on readdir i Julia 1.7. Running the following:

println(readdir("data/"))
println(isdir("data/SST4Fj1_7d384.result"))
println(isdir("best_fit.csv"))

Prints (as expected):

["SST4Fj1_7d384.result", "best_fit.csv"]
true
false

But when running

println(filter(isdir, readdir("data/")))

it prints

String[]

Where I expected ["SST4Fj1_7d384.result"].

You need the full relative path in the list for the filter, not just subfolder name.

So this should be:

println(filter(isdir, readdir("data/", join=true)))
