Assign today date as a due date while creating jira

I am trying to create a jira ticket via curl and here is my command

curl i -D -u POST --data '{“fields”:{“project”:

{“key”: “DEV”}

,“summary”: “changes in boostrap.yml”,“priority”:

{“name”: “Blocker”}

,“duedate”: “2020-12-24”,“description”: “content”,“issuetype”:

{“name”: “Bug”}

}}’ -H “Content-Type: application/json”

Success Criteria-
Pass date as a string and assign it as a due date.
Generally, today’s date can be printed in a Linux command line in this way
date ‘+%Y-%m-%d’

I tried to pass it in different ways but no success.
Please suggest me something.
