cert_file error with aws_ec2 inventory plugin

[James Wallace]

Hey all,

I'm having an issue using the aws_ec2 inventory plugin and I can't seem to find a solution.

ansible 2.8.1

  config file = /home/jwallace/nxt-devops/ansible/ansible.cfg

  configured module search path = [u'/home/jwallace/.ansible/plugins/modules', u'/usr/share/ansible/plugins/modules']

  ansible python module location = /usr/lib/python2.7/dist-packages/ansible

  executable location = /usr/bin/ansible

  python version = 2.7.13 (default, Sep 26 2018, 18:42:22) [GCC 6.3.0 20170516]

production.aws_ec2.yml

plugin: aws_ec2

aws_profile: production

cache: no

regions:

  - us-east-1

~/.aws/credentials

[default]
aws_access_key_id = <same as production>
aws_secret_access_key = <same as production>

[production]
aws_access_key_id = VALUE
aws_secret_access_key = SECRET

Running on Debian Stretch.

# ansible-inventory -i ./production.aws_ec2.yml --list

 [WARNING]:  * Failed to parse /path/to/production.aws_ec2.yml with aws_ec2

plugin: __init__() got an unexpected keyword argument 'cert_file'

 [WARNING]: Unable to parse /path/to/production.aws_ec2.yml as an inventory

source

 [WARNING]: No inventory was parsed, only implicit localhost is available

I don't know where the cert_file argument is coming from!   Any help?
