Causes JavaScriptError in AWS CDK api-gateway

[cn-cit]

Describe the bug

When using the AWS CDK api gateway Model.EMPTY_MODEL (or ERROR_MODEL) the cdk stacks cannot synthesize or deploy.

Expected Behavior

The AWS CDK will not error when using the api gateway Model.EMPTY_MODEL

Current Behavior

@jsii/kernel.SerializationError: Of static property aws-cdk-lib.aws_apigateway.Model.EMPTY_MODEL: Unable to serialize value as aws-cdk-lib.aws_apigateway.IModel
🛑 Failing value is an instance of aws-cdk-lib.aws_apigateway.EmptyModel
EmptyModel { modelId: 'Empty' }
╰── 🔍 Failure reason(s):
╰─ Type 'aws-cdk-lib.aws_apigateway.EmptyModel' not found
at Object.process (/tmp/tmpdm_u1x99/lib/program.js:6194:19)

Reproduction Steps

use a Java cdk project and include this anywhere ...
Map<String, IModel> emptyResponseModels = new HashMap<>(); emptyResponseModels.put("application/json", Model.EMPTY_MODEL);
Use 1.67.0 of this library and the error occurs.

Possible Solution

No response

Additional Information/Context

revert back to 1.66.0 to overcome the problem.

SDK version used

AWS CDK 2.37.1

Environment details (OS name and version, etc.)

Windows 10

Now that CDK 2.41.0+ defines the jsii<2.0.0,>=1.67.0 requirement, it is no longer possible to revert JSII back.

Thanks for reporting. I'm able to reproduce the issue.

This is because I attempted to simplify the assembly load procedure by leveraging runtime-type-information woven in by the compiler... which may return FQNs that are actually not exported by the assembly, triggering this bug.

[RomainMuller]

Interesting - the EmptyModel class does exist and get exported in the library, however it was @deprecated in V1 and is soft-removed from V2... this explains why it still has runtime type information bound to it, but does not exist in the model.

The fix I designed still would work there... The best strategy might be to have RTTI not be woven for deprecated types that will be pruned, but this might end up requiring a huge refactor... This might hence still be the best fix.
