HTML command not working in Custom action input

[krishnanara]

I created a REST API for Jira, I'm trying to add HTML command for the input action 'Description' like below but when I see the result in Jira I see the HTML command not working. Also I added space to each field in Description in the Action inputs seems that didn't work as well. Any idea where I'm wrong?

I'm passing this Description in regex

Request Payload

Jira Output

Could you test without the regex expression and a single line in the description field. 

Check whether you are getting the value at Jira end. It seems Regex character is not getting parsed/escaped .

I tried passing without regex for the other input 'Summary' but I don't see HTML command working there
