CDK Action allows only one Input, but I need two

Hi all,

my project repository setup is like this: . ./lambda ./infrastructure

I am using CDK with Java and I have a maven build both in the "lambda" sub-folder (which contains my lambda code) and in the "infrastructure" folder (which contains my CDK code). In my CodeCatalyst workflow, I was planning to execute my "mvn package" (which builds the lambda jar file) and save this artifact. Then, this artifact needs to be used in the "cdk deploy" action. But as the "cdk deploy" action also needs the "source" input, I would need two inputs.

CodeCatalyst denies that with an error message: Action InfrastructureDeployment declares 2 input artifacts which is more than the maximum count (1)

Does anyone have an idea on how to resolve that?

Thanks! Johannes
