An error occurred (InvalidActionDeclarationException) when calling the UpdatePipeline operation: Input Artifact Bundle MyAppBuild in action ExternalDeploy is not declared as Output Artifact Bundle in

Question

Hi all,
I am trying to create a pipeline in CodePipeline that uses resources from another AWS account. My code pipeline is in DEV account and deployment instances are created through CodeDeploy in PROD account. I made all configurations and updated codepipeline configuration file according this tutorial: https://docs.aws.amazon.com/codepipeline/latest/userguide/pipelines-create-cross-account.html
When I tried to save the pipeline.json file, I got the error below:
`C:\Users\scguser>aws codepipeline update-pipeline --cli-input-json file://pipeline.json

An error occurred (InvalidActionDeclarationException) when calling the UpdatePipeline operation: Input Artifact Bundle MyAppBuild in action ExternalDeploy is not declared as Output Artifact Bundle in any of the preceding actions`

below is a piece of configuration:

```
.....
{
                "name": "PROD_Deploy",
                "actions": [
                    {
                        "inputArtifacts": [
                            {
                                "name": "MyAppBuild"
                            }
                        ],
                        "name": "ExternalDeploy",
                        "actionTypeId": {
                            "category": "Deploy",
                            "owner": "AWS",
                            "version": "1",
                            "provider": "CodeDeploy"
                        },
                        "outputArtifacts": [],
                        "configuration": {
                            "ApplicationName": "prod-app-idp",
                            "DeploymentGroupName": "prod-depl-group-idp"
                        },
                        "runOrder": 1,
                        "roleArn": "arn:aws:iam:::role/cross-account-role-pipeline"
                    }
                ]
            }
```

So, what is going wrong in my side?
Thank you

Hello ,

greeting for the day .

I would like to inform you that this issue generally occurs when any input Artifacts defined in an action of a code pipeline  is not  declared in the preceding action of the same pipeline .

Example  for reference :

```
{
 "pipeline": {
  "roleArn": "arn:aws:iam::111111111111:role/AWS-CodePipeline-Service",
  "stages": [
    {
      "name": "Source",
      "actions": [
        {
          "inputArtifacts": [],
          "name": "Source",
          "actionTypeId": {
            "category": "Source",
            "owner": "AWS",
            "version": "1",
            "provider": "S3"
          },
          "outputArtifacts": [
            {
              "name": "MyApp”.             <<=====Output artifacts is defined with the name MyApp in source action  here . 
            }
          ],
          "configuration": {
            "S3Bucket": "awscodepipeline-demo-bucket2",
            "S3ObjectKey": "aws-codepipeline-s3-aws-codedeploy_linux.zip"
          },
          "runOrder": 1
        }
      ]
    },
    {
      "name": "Beta",
      "actions": [
        {
          "inputArtifacts": [
            {
              "name": "MyApp”.     <============ the same output artifacts MyApp is used as input artifacts here . 
            }
          ],
          "name": "CodePipelineDemoFleet",
          "actionTypeId": {
            "category": "Deploy",
            "owner": "AWS",
            "version": "1",
            "provider": "CodeDeploy"
          },
          "outputArtifacts": [],
          "configuration": {
            "ApplicationName": "CodePipelineDemoApplication",
            "DeploymentGroupName": "CodePipelineDemoFleet"
          },
          "runOrder": 1
        }
      ]
    }
  ],
```

Please note that in this example the input Artifacts called "MyApp" defined in action name   “CodePipelineDemoFleet” is already declared to be available to the output Artifacts of action source .

Now in your example  you have shared with us  ,  I can observe that you have defined the input Artifacts : "MyAppBuild" as mentioned below

```
{
                "name": "PROD_Deploy",
                "actions": [
                    {
                        "inputArtifacts": [
                            {
                                "name": "MyAppBuild”.      
                            }
                        ],
```

Can you please confirm if this   input Artifacts:”MyAppBuild”  is passed as output Artifacts in any other action of your pipeline .  In order to troubleshoot this issue I would suggest to pass the output Artifacts :””MyAppBuild”  from the preceding action of  your code pipeline  which will help you to resolve  this issue

Lastly I hope the above mentioned information sounds good to you  and address your query raised . In case you have any further questions then please feel free to reach out to us , we will be always happy to assist you further .

Have a great day ahead .
