I get an error when trying to get dataset

https://www2.census.gov/geo/tiger/TIGER2019/COUNTY/tl_2019_us_county.zip

or

ftp://ftp2.census.gov/geo/tiger/TIGER2019/COUNTY/tl_2019_us_county.zip

from New HTTP dataset or or New FTP dataset respectively

An error occurred

    Hi,

    Could you clarify what format this data is supposed to be in? If you try downloading the zip manually, the zip consists of a wide ranging set of files: shx, xml, shp, prj, dbf, and cpg. Depending on how the data is supposed to be read, you could either try uploading the file directly or using python to read it, do some preprocessing, and then create the output dataset once it's a dataframe.

    Best,

    Andrew

    File is shapefile type (as per "Working with Shapefiles and US Census Data in DSS" tutorial)

    I did indicate "Shapefile" in the format/schema tab
