Ansible module oracle_user does not set passworts when crypted via ansible_vault

I am using oracle_pdb and oracle_user modules to set up Oracle Databases and users via ansible. This works fine until we use only Standalone databases.
Now I need to set up a CDB/PDB Database. Creation works fine. User setup with a loop on all needed users works also without error.Passwords are stored in an ansible-vault.
But the setted up passwords are not correct.
Encrypting the vault with ansible-vault shows correct password
But login with this passwords rsults in ORA-1017 user/password incorrect.

- name: create deploy user DPLUS_%
  connection: local
  no_log: true
  oracle_user:
    hostname:                "{{ db_hostname }}"
    service_name:            "{{ rcs_pdb_service }}"
    user:                    "{{ db_connect_user }}"
    password:                "{{ db_connect_password }}"
    mode:                    "{{ db_connect_mode }}"
    schema:                  "{{ item.username }}"
    schema_password:         "{{ item.password_vault }}"
    default_tablespace:      "{{ rcs_db_deploy_default_tablespace }}"
    default_temp_tablespace: "{{ rcs_db_deploy_temporary_tablespace }}"
