How to reproduce

Ensure ansible version 2.9.27-150000.1.17.2 is installed.

% echo "{{ 'foo' | from_yaml }}" > test.j2
% ansible all -i "localhost," -c local -m template -a "src=test.j2 dest=./test"


Expected result

Ansible creates file `test` with content “foo”.


Actual result

Ansible fails with:

localhost | FAILED! => {
    "changed": false,
    "msg": "NameError: name 'yaml_load' is not defined"
}
