Create an ec2 instance failed with ec2: error: unrecognized arguments

I am a newbie to the ansible world. I followed your blog, https://djaodjin.com/blog/deploying-on-ec2-with-ansible.blog.html, to create a security group and an ec2 instance. The security group is created successfully, but creating ec2 instance is failed by ec2: error: unrecognized arguments: /home/ec2-user/.ansible/tmp/ansible-tmp-14244… I did set up aws credentials and asnsible variables properly as below

AWS Credentials

export AWS_ACCESS_KEY_ID=xxx
export AWS_SECRET_ACCESS_KEY=xxx

EC2 Environment Variables

export ANSIBLE_HOSTS=/etc/ansible/ec2.py
export EC2_INI_PATH=/etc/ansible/ec2.ini

The files and output are showed as follow. Any ideas for this issue? Thanks for your Help!

$ cat group_vars/all

Variables listed here are applicable to all host groups

key_name: sobrr-staging.pem
aws_region: cn-north-1
ami_id: ami-9e0c9ea7
instance_type: m1.small

$ cat basic-create.yml

For spinning up instances in AWS you don’t need to tell ansible to use the dynamic inventory script. That is something you might want to use later on.
Try unsetting that environment variable.
Also, when running the playbook, you are telling it to use the inventory file /etc/ansible/hosts. Mind showing us what you have in there?
