When using the esp_matter data model (CONFIG_ESP_MATTER_ENABLE_DATA_MODEL=y), attribute::get(endpoint_id, cluster_id, attribute_id) is called during endpoint registration via emberAfExternalAttributeReadCallback. If the cluster doesn't exist on the endpoint, the lookup returns NULL, which is then passed to the two-argument get(cluster_t*, attribute_id) overload that logs at error level. Add a NULL guard in the three-argument overload to return nullptr early, consistent with how command::get(endpoint_id, cluster_id, command_id) already handles this case. Fixes #1692
Espressif's SDK for Matter
Introduction
Espressif's SDK for Matter is the official Matter development framework for ESP32 series SoCs. It is built on top of the open source Matter SDK, and provides simplified APIs, commonly used peripherals, tools and utilities for security, manufacturing and production accompanied by exhaustive documentation. It includes rich production references, aimed to simplify the development process of Matter products and enable the users to go to production in the shortest possible time.
