"Key_load_pubic: Invalid Format"

Experimenting with Terraform and Ansible deployment. I have a TF template that stands up a VPC and ec2 instances in AWS, and uses cloud-init scripts to prepare the instances. I've tried to upload my own SSH keys from Puttygen in the cloud-init scripts but I am receiving a "key_load_public: invalid format" error when testing Ansible. My cloud init is as follows:

#Add Users

If I replace the key using "ssh-keygen", I can use "ssh-copy-id" to the client node with no errors - so I presume something must be wrong with my format coming from Puttygen. The literal format - how the Puttygen public key is laid out in id_rsa.pub - looks exactly the same as the key produced by ssh-keygen. Any thoughts?

I solved it on my own by just copying a key directly from ssh-keygen instead. Not sure why the Puttygen key didn't work, but whatever works!
