I suspect this is caused by https://github.com/r-lib/zip/issues/99 Can you try installing the dev version to see if the problem is fixed?

sebffischer commented 1 year ago

Thanks, this was indeed the problem. Installing the dev version of zip fixed the issue.

I'll bump the required zip version once this dev zip version is on CRAN. We could use a different unzip library in the meantime as a workaround, but not sure if it's worth the effort.

Thanks! And yes, this is probably unnecessary. Maybe it's worth to add some tests to check that the datasets can be downloaded though.
