Should we split up the dataset into smaller files?
Looking at it.
The error seems to say that one of the rows has 12 columns instead of 9

I also tried to run xsv commands on the CSV:
$ xsv count updatedCompanyNews.csv
CSV error: record 1 (line: 2, byte: 75): found record with 9 fields, but the previous record has 7 fields
I think it's a matter of enclosing the strings with ", because they can contain commas.
$ head updatedCompanyNews.csv -n2
companyName, companyUrl, published_at, url, title, main_image, description

Also note that you might want to remove the space after the delimiters, ie: 01Synergy, https -> 01Synergy,https
Thanks @severo for details. I think @fabian339 got it! Our dataset has viewer with 68, 952 paginations!
