How should you go about debugging errors like this? This error happens while parsing a streaming CSV in production after lots of lines. Is there something I could add to logs to get more info about what character the parser is tripping up on? Can't really figure out what the quote / escape option values should be given 'undefined'.

here is the supposed format of my CSV. Is a custom delimiter or escape character necessary?

I think the options quote='"' and escape='"' would be correct according to the Salesforce docs.

Can you pull the file down locally and run it? You can put some logging in the data handler to help find a row number.
