Error when downloading

[priyapatel1]

I'm working through the Sentinel5_NO2_GeoNet.R code. I successfully got to the part where I'm trying to download the code:

r <- NULL
attempt <- 1
while(is.null(r) && attempt <= 10){                                     # tries to download the scenes 10x before script stops
  attempt <- attempt+1
  try(
    r <- datasets()
  )
}

But when I try to download the NetCDF files for TROPOMI, I get the following error:

Column 'download_available' not present, calling check_availabilty() to check download availability of records...
Error in .get(paste0(cred[3], "/odata/v1/Products('", x, "')/", field),  : 
  Not Found (HTTP 404). Failed to process request.

There is no 'download'_available' column - how do I get around this?
