Ansible vars_prompt

I have a error I really can’t figure out why this is happening

My playbook looks as following

ansible-playbook RB2011.yml
ERROR: Syntax Error while loading YAML script, RB2011.yml
Note: The error may actually appear before this position: line 8, column 1

YAML likes spaces, and not tabs; do you have a tab character at the start
of the 'default: "test"' line? If so, change it to spaces, and it should work.

(I was able to reproduce both the failure, and make it succeed, by
switching between a tab and eight spaces.)
