The above gives:

Error in data.table::fwrite(x, file.path(meta$out.dir, csv.name), quote = FALSE,  : 
  No such file or directory: 'WorldBank-facets/geom1_tallrect_ts_chunk1.tsv'. Unable to create new file for writing (it does not exist already). Do you have permission to write here, is there space on the disk and does the path exist?

I expected this should work and create the WorldBank-facets directory, what is going on? This should be added as a test case. Removing out.dir from the above code does work.
