You need to quote the entire jinja expression itself (including the
curlies) if you use it as a yaml value.
Because the single quotes are already using inside the expression,
you;'d have to use the double quotes:
tasks:
- debug:
msg: "Debug> {{ 'foo\nBAR' | regex_search('^bar',
multiline=True, ignorecase=True) }}"
