Hi,

If I run the minimal example in R 3.6.3 it saves the files as shown in the screenshot and I think the console message is fine for this example.

Switching the R Version to e.g. 4.3.1 leads to an error for the ssl connection.

I think this comes from a change in the package for the newer version. This could probably be related with the jsonlite package (if this is used), as they switched the url function and it seems as the issue could come from there. That is how far I could get and hope you can help me to run my code, as I need it on a newer R version.

sig = c("253012" = 0.212,
        "8773" = -0.404,
        "4794" = 0.401,
        "1676" = 0.234,
        "11060" = 0.293,
        "5768" = 0.146,
        "6366" = 0.498,

        )
