How do I resolve the "Resource timed out waiting for creation of physical resource" error when I create a resource using my resource provider type in AWS CloudFormation?

I receive the "Resource timed out waiting for creation of physical resource" error in my stack events when I create a resource using my Resource Provider type in AWS CloudFormation. How can I resolve this error?

Short description

If a resource doesn't return its primaryIdentifier or Physical ID within 60 seconds, then AWS CloudFormation returns the "Resource timed out waiting for creation of physical resource" error. The error happens because the CreateHandler of your resource doesn't return the property specified as the primaryIdentifier in the resource provider schema file organization-service-resource.json.

If you're having issues with other errors related to using a resource provider, see the following articles for additional troubleshooting steps:

Resolution

1.    In your organization-service-resource.json file, confirm that the primaryIdentifier definition follows this format, where Id is a property defined in the properties section:

"primaryIdentifier": [
    "/properties/Id"
]

Note: The resource provider schema file is a JSON file in the organization-service-resource.json format and is located in the root directory of your project.

2.    In your CreateHandler, set the primaryIdentifier property in the model object. For example:

final ResourceModel model = request.getDesiredResourceState();
model.setId("abcdxyz");
return ProgressEvent.<ResourceModel, CallbackContext>builder()
    .resourceModel(model)
    .status(OperationStatus.SUCCESS)
    .build();
