Removing / commenting the csv line (and anything referencing it) will prevent the error from occurring, though I then have to hard code the values it's meant to replace for the script to actually work. If I put the file somewhere else or otherwise make the path to the file wrong, I get a corresponding error about the CSV file not being found, so it at least gets as far as trying to read the file. Nothing in the CSV file is outside the range of [0-9a-zA-Z] except for the '@' in the email field, and the commas and quotation marks formatting the CSV file itself.
