> with replacement value strategy as Record Path Value,
> I am trying to replace square bracket symbol *[* with parenthesis symbol *(*
> in my employeeName column in my csvReader structure with below syntax
> replaceRegex(/employeeName, "[\[]", "(")
> Processor is throwing following exception.
> RecordPathException: java.util.regex.PatternSyntaxException: Unclosed
> character class near index 4 [\\[]
> It worked fine with other special characters such as \{, }, <, >, ;, _, "
> For double qoute ("), i had to use single escape character, for above listed
> other characters, worked fine without any escape character. Other folks in
> Nifi Slack tried \s, \d, \w, \.
> looks like non of them worked.
> replace function worked for replacing [ and ]characters. didn't test any
> other characters.
> Please address resolve the issue.
> Regards,
> Ravi
