Inquire how to avoid "Error: need to escape, but no escapechar set" this problem

Hi, when I tried to use whole raw logfile datasets to the parser, I used the Drain, then it showed this bug.
I wanted to ask if I need to do anything before putting it in the Drain.
But I tried any given 2k datasets, it will not show this bug.
Traceback (most recent call last):
