Hi @Alla Santosh Pavan Kumar and welcome to the Atlassian Community!

"Request header is too large" clearly indicates that a http header received by Jira is too large. How this happens is not clear from your log. Are you running your own script or calling an endpoint manually?

Please explain what you are trying to do and when you are getting this error.
