Describe the bug
When calling a model.register() method with model_life_cycle param, a TypeError: Object of type ModelLifeCycle is not JSON serializable is encountered.
To reproduce
Create a new model
model = Model(
image_uri="account.dkr.ecr.region.amazonaws.com/repo:tag",
role="arn:aws:iam::account:role/name",
sagemaker_session=PipelineSession
)
Call model.register()
model.register(
content_types="application/json",
response_types="application/json",
model_package_group_name="somePackageGroupName",
model_life_cycle=ModelLifeCycle(
stage="someStage",
stage_status="someStatus",
stage_description="someDescription"
)
)
Expected behavior
model.register() should not throw TypeError when called with model_life_cycle params.

System information
A description of your system. Please provide:
- SageMaker Python SDK version: 2.244.2
- Framework name (eg. PyTorch) or algorithm (eg. KMeans): N/A
- Framework version: N/A
- Python version: 3.11
- CPU or GPU: N/A
- Custom Docker image (Y/N): N
Suggested fix
Issue could be due to not converting the ModelLifeCycle class object into dict first since json.dumps() accepts a dict.
Replace model_package_args["model_life_cycle"] = model_life_cycle with model_package_args["model_life_cycle"] = model_life_cycle._to_request_dict()
