Troubleshooting InvalidActionDeclarationException in AWS Code Pipeline

Introduction

Welcome to our technical blog where we will dive deep into troubleshooting the InvalidActionDeclarationException in AWS Code Pipeline. Code Pipeline is a robust service provided by Amazon Web Services (AWS) that allows you to automate your software release process. However, encountering exceptions like InvalidActionDeclarationException can be frustrating. In this article, we will explore this exception, its possible causes, and steps to resolve it effectively.

What is InvalidActionDeclarationException?

The InvalidActionDeclarationException is an exception that occurs when there is an issue with the declaration of an action within a pipeline. This exception is specific to the com.amazonaws.services.codepipeline.model package in AWS Code Pipeline.

Common Causes

There could be several reasons behind the InvalidActionDeclarationException in AWS Code Pipeline. Let’s explore some common causes:

1. Missing or Invalid Inputs: One of the most common causes is incorrect or missing input declarations within the action configuration.

Example:

ActionDeclaration actionDeclaration = new ActionDeclaration()
        .withName("MyAction")
        .withActionTypeId(new ActionTypeId().withCategory("InvokeLambdaFunction"))
        // Missing inputPaths and outputPaths
        .withConfiguration(new HashMap<>());

1. Missing or Invalid Action Type: The provided action type may not exist or may be incorrect, resulting in an exception.

Example:

ActionDeclaration actionDeclaration = new ActionDeclaration()
        .withName("MyAction")
        .withActionTypeId(new ActionTypeId().withCategory("CustomCategory"))
        // Invalid action type
        .withConfiguration(new HashMap<>());

Resolving InvalidActionDeclarationException

Now that we have explored the common causes of the InvalidActionDeclarationException, let’s move on to resolving this issue effectively. Here are some steps you can take:

1. Review Action Configuration: Double-check the action declaration and ensure that all required fields, such as name, inputPaths, outputPaths, and actionTypeId, are properly specified.

Example:

ActionDeclaration actionDeclaration = new ActionDeclaration()
        .withName("MyAction")
        .withActionTypeId(new ActionTypeId().withCategory("InvokeLambdaFunction"))
        .withInputArtifactDetails(new ArtifactDetails().withMaximumCount(1))
        .withOutputArtifactDetails(new ArtifactDetails().withMaximumCount(1))
        .withConfiguration(new HashMap<>());

1. Verify Action Types: Confirm that the action type being used is correct and valid. Review the AWS Documentation for a list of available action types and their required configuration properties.

Example:

ActionDeclaration actionDeclaration = new ActionDeclaration()
        .withName("MyAction")
        .withActionTypeId(new ActionTypeId().withCategory("AWS"))
        .withConfiguration(new HashMap<>());

1. Check Action Order: Ensure that the actions in your pipeline are ordered correctly. Actions relying on other actions should be placed after the required actions.

Example:

PipelineDeclaration pipelineDeclaration = new PipelineDeclaration()
        .withName("MyPipeline")
        .withStages(
                new StageDeclaration()
                        .withName("MyStage")
                        .withActions(
                                // Required action must appear first
                                new ActionDeclaration().withName("RequiredAction"),
                                // Dependent action
                                new ActionDeclaration().withName("DependentAction")
                        )
        );

1. Review IAM Permissions: Verify that the IAM role associated with your pipeline has the necessary permissions to perform the actions specified.
