switch to oracle user from root using su method - timeout (62s) waiting for privilege escalation prompt

Question

I'm able to ssh to an oracle server manually without password, sudo to root and then su to oracle user. The same I'm trying to do with ansible, but getting timeout (62s) waiting for privilege escalation prompt with su to oracle user.

Manual

[testuser@ansibleServer ans_playbook]$ ssh ansibleUser@server1
-bash: TMOUT: readonly variable
[ansibleUser@server1 ~]$ sudo su - root
Last login: Wed Mar  9 15:45:36 IST 2022 on pts/1
-bash: TMOUT: readonly variable
[root@server1 ~]# su - oracle
Last login: Wed Mar  9 18:14:34 IST 2022
-bash: TMOUT: readonly variable
server1:MAMO1:oracle:/home/oracle>pwd
/home/oracle
server1:MAMO1:oracle:/home/oracle>exit
logout
[root@server1 ~]# exit
logout
[ansibleUser@server1 ~]$ exit
logout
Connection to server1 closed.
[testuser@ansibleServer ans_playbook]$

Ansible

    - name: get user name
      set_fact:
        user: "{{ user_name.stdout|regex_replace( '(\\w+).*','\\1' ) }}"
      when: user_name.rc == 0

        rman target / <<EOF
        list archivelog all;
        EOF
      register: archivelog
      become: true
      become_method: su
      become_flags: "--login"
      become_user: "{{ user }}"

            

Error

With operation task getting the below error. Tried without --login, but failed with same error.
