+== Exceptions tab fails to load
+
+On December 5, 2024, it was discovered the {sec-serverless} **Exceptions** tab fails to load when exceptions contain comments with newline characters (`\n`). For details, refer to ({kibana-issue}201820[#201820]).
+
+*Custom rules workaround* + 
+
+. Go to the **Rules** page, then <<import-export-rules-ui,export>> the rule or rules with the exception lists with newline characters. 
+. Open the `.ndjson` file, then remove the newline characters from the `comments`.
+. Go to the **Rules** page, then <<import-export-rules-ui,re-import>> the rules. Make sure to select **Overwrite existing exception lists with conflicting "list_id"**.
+
+*Prebuilt rules workaround* + 
+
+. For the exception lists with newline characters, fetch the IDs associated with the rule.
+.. Go to the **Rules** page.
+.. Open the rule details, then go to the page URL.
+.. Copy the URL id string. 
++
+For example, in the http://host.name/app/security/rules/id/167a5f6f-2148-4792-8226-b5e7a58ef46e URL, copy the `167a5f6f-2148-4792-8226-b5e7a58ef46e` id string.
+.. To specify the `id` when fetching the rule details, use the {api-kibana-serverless}/operation/operation-readrule[retrieve a detection rule API]:
++
+[source,console]
+----
+curl -H 'Authorization: ApiKey API_KEY_HERE' -H 'kbn-xsrf: true' -H 'elastic-api-version: 2023-10-31' KIBANA_URL/api/detection_engine/rules?id=167a5f6f-2148-4792-8226-b5e7a58ef46e
+----
++
+The JSON response contains the `id`, `list_id`, and `namespace_type` values in the `exceptions_list` key: 
++
+[source,console]
+----
+{
+  "id": "167a5f6f-2148-4792-8226-b5e7a58ef46e",
+  "exceptions_list": [
+    {
+      "id": "490525a2-eb66-4320-95b5-88bdd1302dc4",
+      "list_id": "f75aae6f-0229-413f-881d-81cb3abfbe2d",
+      "namespace_type": "single"
+    }
+  ]
+}
+----
++
+. To retrieve the exception list with newline characters, use the export exceptions API with the `id`, `list_id`, and `namespace_type` values:
++
+[source,console]
+----
+curl -XPOST -H 'Authorization: ApiKey API_KEY_HERE' -H 'kbn-xsrf: true' -H 'elastic-api-version: 2023-10-31' 'KIBANA_URL/api/exception_lists/_export?list_id=f75aae6f-0229-413f-881d-81cb3abfbe2d&id=490525a2-eb66-4320-95b5-88bdd1302dc4&namespace_type=single' -o list.ndjson
+----
++
+. Open the `.ndjson` file, then remove the newline characters from the `comments[].comment` values.
+. Go to the <<security-shared-exception-lists,**Shared Exception Lists**>> page.
+. To re-import the exception list, use the **Import exception lists** option.
++
+Since the exception list exists, the import fails, and the option to overwrite the existing list appears. 
+. Select the overwrite option, then resubmit the request to import the exception list.
+
+NOTE: To export and re-import exceptions for the Elastic Endpoint rule, use the <<security-shared-exception-lists,**Shared Exception Lists**>> page.
