Code deploy Permission in aws using Bitbucket Pipeline

https://repost.aws/questions/QUo7aycUzLTBWNweeXbtrODA/ci-cd-automatic-deployment-from-bitbucket-to-aws-ec2-window-instance#ANAfUvgXdTQ9GSElByyi9Bmw

I am strggling to deploy my first application via Bitbucket pipline to EC2 Windows server. I am getting following error in bitbucket pipline. ERROR: Deployment failed. Fetching deployment information... stack overflow

I have checked the code deploy log it It says Error polling for host commands: Aws::Errors::MissingCredentialsError - unable to sign request without credentials set I have also checked the code deploy agent on the instance which is in runnung state.

Please help!! Thank you!
