@rahulbajaj0509, the Redmine ticket used is for a different project than the one associated with this GitHub repository. Please either:

• check #28196: hammer auth login oauth throws undefined method `request_uri' on empty Openidc Provider Token Endpoint is the correct one
• move ticket #28196 from Foreman to the Hammer CLI project
• or file a new ticket in the Hammer CLI project

If changing the ticket number used, remember to update the PR title and the commit message (using git commit --amend).

@rahulbajaj0509 thanks!, LGTM. I did some very basic testing and it fixed the issue for me.
