Known issues

gotchaPackage not updated since 2019 and has low downloads; consider alternatives like CDK or Terraform for production deployments.

fix

Use AWS CDK or Terraform with Java runtime.

affects: >=0.0.0

gotchaOnly supports Java 8; Java 11+ features may break.

fix

Ensure your code targets Java 8 bytecode.

affects: >=0.0.0

gotchaRequires Request.java and Response.java to have getters/setters; otherwise compilation fails.

fix

Include proper JavaBean patterns (getters, setters, no-arg constructor).

affects: >=0.0.0

gotchaCLI options are case-sensitive and not validated; typo in --aws-role will cause silent failure.

Request.java or Response.java missing correct getters/setters or no-arg constructor

fix

Ensure both classes have getter for each field, setter for each field, and a public no-argument constructor.
