1. Minimal reproduce step (Required)

Run this minimal example to reproduce the issue.

import oam

_params = {
	env = "template.dev",
	name = "application-env",
	release_version = "20241111",
}

[
	oam.Application {
		metadata = {
			# init-application-env
			name = _params.name
			namespace = "_params.env.namespace"
			annotations = {
				"app.oam.dev/publishVersion" = _params.release_version
			}
		}
		spec = {
			components = [{
				$type = "k8s-objects"
				name = _params.name
				properties.objects = [{
					apiVersion = "v1"
					kind = "ConfigMap"
					metadata.name = _params.name
					data = {
						LOGGING_CONFIG = "classpath:log4j2-spring-local.xml"
						OTEL_EXPORTER_OTLP_ENDPOINT = "fdsa"
						OTEL_INSTRUMENTATION_RUNTIME_TELEMETRY_ENABLED = "false"
						SPRING_CLOUD_CONFIG_LABEL = "dev/init-dev"
						SPRING_PROFILES_ACTIVE = "dev4"
					}
				}, {
				  apiVersion = "v1"
				  kind = "Secret"
				  $type = "Opaque"
				  metadata.name = "application-env"
				  stringData = {
				    OTEL_EXPORTER_OTLP_HEADERS = "fdsa"
				  }
				}]
			}]

			policies = [{
				$type = "topology"
				name = metadata.namespace
				properties = {
					clusters = ["_params.env.cluster"]
				}
			}]
		}
	}
]

2. What did you expect to see? (Required)

Compilation successful, output the correct OAM YAML resource.

3. What did you see instead (Required)

Compilation failed.

4. What is your KCL components version? (Required)

Hello, you can use the following code.

import oam
import manifests

_params = {
	env = "template.dev",
	name = "application-env",
	release_version = "20241111",
}

manifests.yaml_stream([
	oam.Application {
		metadata = {
			# init-application-env
			name = _params.name
			namespace = "_params.env.namespace"
			annotations = {
				"app.oam.dev/publishVersion" = _params.release_version
			}
		}
		spec = {
			components = [{
				$type = "k8s-objects"
				name = _params.name
				properties.objects = [{
					apiVersion = "v1"
					kind = "ConfigMap"
					metadata.name = _params.name
					data = {
						LOGGING_CONFIG = "classpath:log4j2-spring-local.xml"
						OTEL_EXPORTER_OTLP_ENDPOINT = "fdsa"
						OTEL_INSTRUMENTATION_RUNTIME_TELEMETRY_ENABLED = "false"
						SPRING_CLOUD_CONFIG_LABEL = "dev/init-dev"
						SPRING_PROFILES_ACTIVE = "dev4"
					}
				}, {
				  apiVersion = "v1"
				  kind = "Secret"
				  $type = "Opaque"
				  metadata.name = "application-env"
				  stringData = {
				    OTEL_EXPORTER_OTLP_HEADERS = "fdsa"
				  }
				}]
			}]

			policies = [{
				$type = "topology"
				name = metadata.namespace
				properties = {
					clusters = ["_params.env.cluster"]
				}
			}]
		}
	}
])
