I have a look that maybe one of the hash records is having trouble how to manage the metonym and error message.
To see if the file loads the boot and anywhere is difficult buy the boot reject
Do you have the CSV Reader configured correctly for the file its trying to read? Have you tried the File Reader node? What does the log file tell you? What version of KNIME are you using? Can you share some sample data which would make it easier to find some help?
