I am attempting to follow this example of setting up an AWS Pipeline for use across multiple accounts. I have the four different accounts set up. I've followed through on each step of the process successfully. No commands are generating any errors. The pipeline completes successfully. I can then connect to the pipeline and commit my code changes. In short, every single step up to the final one works as written in the documentation.

However, I'm then presented with an error on the initial trigger of the code commit:

Insufficient permissions The service role or action role doesn’t have the permissions required to access the AWS CodeCommit repository named dbmigration. Update the IAM role permissions, and then try again. Error: User: arn:aws:sts::12345678912:assumed-role/my-pipeline-CodePipelineRole-1UPXOXOXO1WD0H/987654321 is not authorized to perform: codecommit:UploadArchive on resource: arn:aws:codecommit:us-east-2:123456789:dbmigration

The AWS Account I used to create the pipeline is not the root account, but an IAM Administrator login with admin privileges across the account. I've tried adding AWSCodeCommitFullAccess and AWSCodePipelineFullAccess, which I would have thought would have been part of Administration anyway. However, that didn't change anything.

My assumption is I've done something horribly wrong, but I'm not able to identify what that is. Any suggestions for better troubleshooting, let alone suggestions on how to fix it would be most welcome.

The code used to create the pipeline, again, run using the IAM login, Administrator, from a fourth AWS account, is as follows:

I have angular application and the back end was on node.js. Now I want to deploy the application to AWS EC2 instance from bitbucket repository using bit bucket pipeline and AWS Code Deploy.

When I am trying to install AWS code deploy agent in EC2 instance I am getting forbidden error.(403 error code)

It is a permission issue and I am missing some configure related permission.

I am trying to deploy it with the help of AWS Code Deploy by following the below article.
