InvalidArgsException in AWS Certificate Manager: A Deep Dive
InvalidArgsException is an important exception class found in the com.amazonaws.services.certificatemanager.model package of AWS Certificate Manager. In this article, we will explore the InvalidArgsException and understand its significance in AWS Certificate Manager. We will also dive into code examples, best practices, and explore various use cases.
What is InvalidArgsException?
InvalidArgsException is an exception class that indicates when one or more input arguments provided to a method in AWS Certificate Manager are invalid or inappropriate. It is a subclass of the AmazonCertificateManagerException class and is typically thrown when there is a problem with the input parameters provided to an API call.
When is InvalidArgsException Thrown?
InvalidArgsException can be thrown in multiple scenarios when working with AWS Certificate Manager. Some common scenarios include:
1. Invalid Domain Validation Options
When requesting a certificate, AWS Certificate Manager requires appropriate domain validation options. If the provided options are invalid, the InvalidArgsException is thrown. For example, consider the following code snippet:
1
2
3
4
5
6
7
8
9
try {
String domainName = "example.com";
RequestCertificateRequest request = new RequestCertificateRequest()
.withDomainName(domainName)
.withDomainValidationOptions(new ArrayList<>());
RequestCertificateResult result = acmClient.requestCertificate(request);
} catch (InvalidArgsException e) {
System.out.println("Invalid domain validation options provided.");
}
2. Invalid Input for DNS Validation
DNS validation is one of the ways to validate domain ownership. In case of an invalid input parameter for DNS validation, InvalidArgsException is thrown. Here’s an example:
1
2
3
4
5
6
7
8
9
10
try {
String domainName = "example.com";
CreateCertificateRequest request = new CreateCertificateRequest()
.withDomainName(domainName)
.withValidationMethod(ValidationMethod.DNS)
.withDomainValidationOptions(new ArrayList<>());
CreateCertificateResult result = acmClient.createCertificate(request);
} catch (InvalidArgsException e) {
System.out.println("Invalid input for DNS validation.");
}
3. Invalid Certificate Identifier
If the provided certificate identifier is invalid when performing an action like deleting or retrieving a certificate, InvalidArgsException is thrown. Here’s an example:
1
2
3
4
5
6
7
8
try {
String certificateArn = "arn:aws:acm:us-west-2:123456789012:certificate/invalid-id";
DeleteCertificateRequest request = new DeleteCertificateRequest()
.withCertificateArn(certificateArn);
DeleteCertificateResult result = acmClient.deleteCertificate(request);
} catch (InvalidArgsException e) {
System.out.println("Invalid certificate identifier provided.");
}
Handling InvalidArgsException
When handling the InvalidArgsException, it is important to identify the root cause and take appropriate actions. Some of the common strategies include:
Validate Input Parameters: Ensure that you are providing proper and valid input parameters to the API calls. Check the AWS Certificate Manager documentation for the expected format and options.
Validate Domain Validation Options: When requesting or creating a certificate, validate the domain validation options to ensure they are correct. Refer to the AWS Certificate Manager developer guide for more details.
Check Certificate Identifier: Double-check the certificate identifier when performing actions like deleting or retrieving a certificate. Ensure that you have the correct ARN or ID for the certificate.
Conclusion
