CodePipeline unable to update pipelineType or triggers using aws-cli

Hi there,

I am having some difficulty in upgrading an existing CodePipeline using AWSCLI.

Specifically I want to set the Pipeline Type to V2 and configure git triggers to watch new tags beginning with v*.

I have done this manually through the AWS console, but I want to automate this as part of my devops.

The issue

Despite the documentation for awscli update-pipeline and API UpdatePipeline clearly demonstrating the use of pipelineType and triggers objects, I get the following error when attempting to set these

# $CODEPIPELINE_JSON is modified input of `aws codepipeline get-pipeline` command, see below
aws codepipeline update-pipeline --profile $AWS_PROFILE --cli-input-json "$CODEPIPELINE_JSON" --no-cli-pager
Parameter validation failed:
Unknown parameter in pipeline: "pipelineType", must be one of: name, roleArn, artifactStore, artifactStores, stages, version
Unknown parameter in pipeline: "triggers", must be one of: name, roleArn, artifactStore, artifactStores, stages, version

Can anyone advise where I am going wrong, or any other way to achieve this progmatically?

At the time of writing, CloudFormation doesn't support setting the pipelineType or triggers for AWS::CodePipeline::Pipeline either, and most importantly, whenever I update the cloudformation template, the CodePipeline gets reverted back to V1 and I lose the ability to watch for new tags. Not great in a prod environment.

Below is a redacted copy of $CODEPIPELINE_JSON with the pertinent values included

{
  "pipeline": {
    "name": "my-prod-pipeline-name",
    "roleArn": "arn:aws:iam::XXXXXXXXXXXX:role/my-prod-pipeline-role",
    "artifactStore": {
      "type": "S3",
      "location": "xxxxxxxxxxxxxxxxxxxxxxxxxxxxx"
    },
    "stages": [
        { /* snip ...*/ }
    ],
    "version": 19,
    "pipelineType": "V2",
    "triggers": [
      {
        "providerType": "CodeStarSourceConnection",
        "gitConfiguration": {
          "sourceActionName": "GitHubSourceActionForProd",
          "push": [
            {
              "tags": {
                "includes": [
                  "v*"
                ],
                "excludes": []
              }
            }
          ]
        }
      }
    ]
  }
}

and i'm using a shell script akin to this, to perform the update by modifying the JSON structure of the existing pipepline:

#!/usr/bin/env bash

CODEPIPELINE_NAME="my-prod-pipeline-name"
AWS_PROFILE="my-profile"

# Retrieve existing codepipeline
CODEPIPELINE_JSON=$(aws codepipeline get-pipeline --name $CODEPIPELINE_NAME --profile $AWS_PROFILE --no-cli-pager)

# Remove the "metadata" section from $CODEPIPELINE_JSON
CODEPIPELINE_JSON=$(echo "$CODEPIPELINE_JSON" | jq 'del(.metadata)')

# Add the pipelineType and triggers to existing JSON 
NEW_JSON='{
  "pipelineType": "V2",
  "triggers": [
    {
      "providerType": "CodeStarSourceConnection",
      "gitConfiguration": {
        "sourceActionName": "GitHubSourceActionForProd",
        "push": [
          {
            "tags": {
              "includes": ["v*"],
              "excludes": []
            }
          }
        ]
      }
    }
  ]
}'

# Add the new JSON to the pipeline object
CODEPIPELINE_JSON=$(echo "$CODEPIPELINE_JSON" | jq --argjson newJson "$NEW_JSON" '.pipeline += $newJson')

# Output JSON for debugging purposes
echo "$CODEPIPELINE_JSON"

# Perform the update
aws codepipeline update-pipeline --profile $AWS_PROFILE --cli-input-json "$CODEPIPELINE_JSON" --no-cli-pager
