Error when launching

I get this error every time I run ./test-factor.sh. I believe it is to do with the line instance_id: “{{ hostvars[groups[ami_builder.group][0]].ec2_id }}” in build-finish.yml. Any help would be much appreciated.

./test-factor.sh

Unfortunately we will not be able to attend to this for two weeks or so, but this error indicates that ansible couldn't find any hosts on which to run.

If you don't want to change the code, you can fix it using 'ansible<2.2' and it will work.

How do you change the configuration so that it uses an older version of Ansible?

You could try using a virtual env and installing via pip with pip install 'ansible<2.2'.
