This leads to inconsistencies in the JSON structure, causing downstream processes that rely on the presence of the `CRUDOperations` key to fail or behave unexpectedly.\n\n---\n\n### **Steps To Reproduce**  \n1. Create a `CallSite` object with the `CRUDOperations` field set to `null`.  \n2. Serialize the `CallSite` object using Gson.  \n3. Inspect the resulting JSON output.  \n4. Observe that the `CRUDOperations` key is missing from the JSON.  \n\n---\n\n### **Observed behavior**  \nThe `CRUDOperations` key does not appear in the JSON when its value is `null`, which disrupts systems expecting a consistent schema with this key present.\n\n---\n\n### **Expected behavior**  \nThe `CRUDOperations` key should appear in the JSON output, even when its value is `null`, to maintain a consistent schema for all `CallSite` objects.\n\n---\n\n### **Error Log**  \nNot applicable, as the issue is related to the absence of expected fields in the JSON structure rather than an explicit error.\n\n---\n\n### **Environment (please complete the following information):**  \n- OS: Fedora 41  \n- Version of Java: 21  \n- Version of Gson: 2.10.1  \n- Version of Maven/Gradle: N/A  \n\n---\n\n### **Additional context**  \nThis issue can be resolved by configuring Gson to include `null` values during serialization using `new GsonBuilder().serializeNulls().create()`.","author":{"url":"https://github.com/rahlk","@type":"Person","name":"rahlk"},"datePublished":"2025-02-08T03:14:06.000Z","interactionStatistic":{"@type":"InteractionCounter","interactionType":"https://schema.org/CommentAction","userInteractionCount":1},"url":"https://github.com/108/codeanalyzer-java/issues/108"}
