‼️ NOTICE | apigateway: Unable to serialize value as `aws-cdk-lib.aws_apigateway.IModel`

Please add your +1 👍 to let us know you have encountered this
-----------------------------------

### Status: __RESOLVED__

### Overview:

Users of CDK in any language other than TS/JS cannot use values that return an instance of a deprecated class.

### Affected Versions

Any version greater or equal to 2.41.0 

#### Complete Error Message:

```console
144 | jsii.errors.JavaScriptError:
145 | **@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**
146 | ├── 🛑 Failing value is an instance of aws-cdk-lib.aws_apigateway.EmptyModel
147 | │      EmptyModel { modelId: 'Empty' }
148 | ╰── 🔍 Failure reason(s):
149 | ╰─ Type 'aws-cdk-lib.aws_apigateway.EmptyModel' not found
150 | at Object.process (/tmp/tmpdm_u1x99/lib/program.js:6194:19)
```

### Workaround:

Case by case workarounds, such as ones described [here](https://github.com/aws/aws-cdk/issues/21902#issuecomment-1252535213).

You could also pin the jsii client libraries to 1.68.0:

#### Python

```console
jsii==1.68.0
```

#### Java

```xml
<dependency>
  <groupId>software.amazon.jsii</groupId>
  <artifactId>jsii-runtime</artifactId>
  <version>1.68.0</version>
</dependency>
```

#### Golang

```console
require (
	github.com/aws/jsii-runtime-go v1.68.0
)
```

#### C#

```console
Amazon.JSII.Runtime==1.68.0
```

### Solution:

TBD

### Describe the bug

I have a CDK v2 project in python and the "cdk synth" command is now suddenly failing.  Below is the error from CodeBuild log, this just suddenly started after my latest commit triggered a build of my CDK Pipeline where I was using CDK 2.39.0.  I also am now seeing the synth step failing on my local dev environment as well and installing CDK 2.40.0 did not seem to resolve the error either.

### Expected Behavior

I am expecting the "cdk synth" command to complete successfully.

### Current Behavior

Currently the "cdk synth" step is failing to complete.  Below is the full log from CodeBuild during my pipeline execution:
