Unlocking the Power of InvalidInputException in AWS Organizations
Introduction
Welcome to this in-depth guide on InvalidInputException in the com.amazonaws.services.organizations.model package of AWS Organizations. In this article, we will explore this powerful exception, understand its purpose, and examine its usage through various code examples. Whether you’re a beginner or an experienced AWS user, this comprehensive guide will equip you with the knowledge to handle input validation errors with ease.
Understanding InvalidInputException
InvalidInputException is an exception class provided by the AWS Organizations service. It is thrown when an API request to AWS Organizations fails due to invalid input provided by the caller. Invalid input can include incorrect parameters, malformed JSON, missing required fields, or any other input-related issues.
This specialized exception is designed to help developers troubleshoot and rectify input errors effectively. By catching and analyzing InvalidInputException, you can identify the exact cause of failure and take appropriate corrective measures.
Common Causes of InvalidInputException
Before delving into code examples, it’s essential to understand the common causes that trigger InvalidInputException in AWS Organizations. Common causes include:
Missing required parameters: For certain API requests, specific parameters are mandatory. Failing to provide these required parameters will result in an InvalidInputException.
Incorrect parameter format: Certain API requests require parameters to adhere to a specific format (e.g., date, timestamp). Providing parameters in an incorrect format will trigger an InvalidInputException.
Invalid JSON structure: When passing data in API requests, the JSON structure must be well-formed and valid. Any issues with the JSON structure will result in an InvalidInputException.
Invalid values: AWS Organizations API requests often have predefined acceptable values for certain parameters. Providing an invalid value will trigger the InvalidInputException.
Handling InvalidInputException with Example Code
To showcase how to handle InvalidInputException effectively, let’s dive into some code examples:
Example 1: Missing Required Parameters

try {
CreateOrganizationalUnitRequest request = new CreateOrganizationalUnitRequest();
request.setParentId("12345"); // Required parameter missing
request.setOrganizationalUnitName("MyOU");
CreateOrganizationalUnitResult result = organizationsClient.createOrganizationalUnit(request);
} catch (InvalidInputException e) {
// Handle the specific error when required parameters are missing
System.out.println("Error: Required parameters missing - " + e.getMessage());
}
In this example, we attempt to create an organizational unit without providing the required parentId parameter. As expected, this triggers an InvalidInputException. By catching this exception, we can gracefully handle the error and provide meaningful feedback or take the necessary actions.
Example 2: Incorrect Parameter Format

try {
RegisterDelegatedAdministratorRequest request = new RegisterDelegatedAdministratorRequest();
request.setAccountId("123456789012"); // Invalid account ID format
request.setServicePrincipal("organizations.amazonaws.com");
organizationsClient.registerDelegatedAdministrator(request);
} catch (InvalidInputException e) {
// Handle the specific error when the account ID format is incorrect
System.out.println("Error: Invalid account ID format - " + e.getMessage());
}
Here, we attempt to register a delegated administrator but supply an invalid account ID. The InvalidInputException alerts us to the incorrect format. We can then take the necessary action to correct the account ID or provide suitable user feedback.
Example 3: Invalid JSON Structure

try {
UpdatePolicyRequest request = new UpdatePolicyRequest();
// Invalid JSON structure: missing closing brace }
request.setPolicyId("p-0123456789abcdefg");
request.setContent("{\"version\": \"2012-10-17\",\"statement\": [{\"some\": \"data\"]");
organizationsClient.updatePolicy(request);
} catch (InvalidInputException e) {
// Handle the specific error when the JSON structure is invalid
System.out.println("Error: Invalid JSON structure - " + e.getMessage());
}
In this example, we attempt to update a policy with an invalid JSON structure. The InvalidInputException provides valuable insight into the issue. By catching this exception, we can rectify the JSON structure or inform the user of the problem.
Example 4: Invalid Values

try {
MoveAccountRequest request = new MoveAccountRequest();
request.setAccountId("123456789012");
request.setSourceParentId("ou-1abc2d34"); // Invalid source parent ID
request.setDestinationParentId("ou-0abc4d56");
organizationsClient.moveAccount(request);
} catch (InvalidInputException e) {
// Handle the specific error when an invalid source parent ID is provided
System.out.println("Error: Invalid source parent ID - " + e.getMessage());
}
In this example, we try to move an account with an invalid source parent ID. The InvalidInputException highlights the specific parameter causing the error. We can use this information to correct the source parent ID or display a relevant error message.
