Following the example given in the README of the github repository of this package ([https://github.com/mhudecheck/Sentinel.jl](https://www.stackoverflow.com/)), the saveList() function creates the /.img\_cache folder but then it prints a “false” value, but it stays as if it was in an eternal loop.

Do you know why could this be happening?

This is the code I am running. The json credentials are for accesing to the Sentinel-2 database of google cloud.

```julia
`

`using Sentinel
using GoogleCloud

creds = JSONCredentials("sentinel_2.json")
session = GoogleSession(creds, ["devstorage.full_control"])
set_session!(storage, session)

l2aList = safeList() # Outputs a DataFrame Array``

```

I have tried creating the /.img\_cache for myself, not letting the program to do it by itself, but it gives the same problem.

Just in case it is useful information, I have a SSD aditional to a HDD in my computer, with conda installed in the SSD.
