Recently I faced the below error when I tried to use some variables which I initialized on a ansible vault file.
My code is shown below. It just prints some values retrieved from a vault.
ansible-playbook vault.yml --vault-password-file=vault_key
While deploying the playbook the below error appears:
ERROR! variable files must contain either a dictionary of variables, or a list of dictionaries. Got: user_password:password database_password:password ( <class ‘ansible.parsing.yaml.objects.AnsibleUnicode’>)
In order to resolve issue, you should just leave a blank between dictionary key and value.
Deploy again your playbook and the result will be successful.
