Hi all,

I've just upgrade SpringBoot to version 2.1.3.

I have a Javascript function to check special character as below

function checkSpecialChar(str){
return !/[~`!#$%^&*+=-[]\';,/{}|\":<>?]/g.test(str);
}

I received an error at runtime

org.thymeleaf.templateparser.text.TextParseException: (Line = 210, Column = 1) Incomplete structure:

Can anyone please show me the reason?

Thanks in advance,
