This was just working a day ago but now throwing exception. I've pasted regex into online verifier and it looks good?

What am I missing?

<input type="text" class="form-control" name="nickname" id="nickname" value="Alicia"
       pattern="[\w\s\-\(\)\!\,\.]{3,45}">

Pattern attribute value [\w\s\-\(\)\!\,\.]{3,45} is not a valid regular expression: Uncaught SyntaxError: Invalid regular expression: /[\w\s\-\(\)\!\,\.]{3,45}/: Invalid escape

Thanks for the help!

Looks valid to me though Chrome does indeed plain.

In any case, you don't need to escape all those characters within a character class. You should be able to use

pattern="[\w\s()!,.-]{3,45}"

which seems to work ok for me.
