dir.create(tmp_dir) : invalid 'path' argument #111

First of all, thank you for such brilliant work. This library is being very helpful. Presently, I am downloading sentinel-3 imagery. Almost everything is working well. However, when it gets to seect_timeseries function, I receive an unusual error. I tried debugging, but I could not find the subfunctions that this function is calling. Following is the screenshot of the error.

I am passing the path as:
set_archive('ArchivePath')
I would greatly appreciate if you can please direct me to the direction, or you can look into this.
