Regex validation is not working on the User Creation Request form

[Yurii]

On the User Creation Request form I have a field for users.customproperty35 and I want to validate user input by regex. According documentation (https://docs.saviyntcloud.com/bundle/EIC-Admin-v2022x/page/Content/Chapter14-Password-Management/Und...), I created following regex to limit user input by small chars, digits, point and dash:

[a-z0-9-.]{1,20}

But, despite that, I'm still able to create user requests with out of the scope chars.
For example, I created the request with customproperty35 = test100#_l
In this case, chars "#" and "_" should not pass regex, but they do. 

Why my regex is not working?

Hi @Yurii ,

Can you check using the following expression?

^[a-z0-9-.]{1,20}$

Thank you @armaanzahir ! Now it's working.
