How to set character limits on a custom field?

[Amy Nguyen]

Hi, 

I am trying to set a character limit on a custom field to be less than 750 characters. It could be from 1 character up to 750 characters including special characters like $, %,.... This is the regular expression I used but it did not work

[A-z a-z 0-9]{1,750}

What am I missing? 

Thank you!

Amy

Hi @Amy Nguyen 

I'm not sure where you are setting that as it's not a "default" Jira field. I'm also assuming Jira server with this suggestion but have a look at Regex Custom Fields plugin for Jira Server. I use it for just this kind of thing in my instance.

I am setting a validator during the create transition using "Regular Expression Check (JSU).
