…NotificationConfigs RestTransport.buildListTasksQueryString() iterated all fields of ListTasksParams except statusTimestampAfter, which was silently dropped from every GET /tasks request, making the server-side timestamp filter unreachable from the Java client. RestTransport.listTaskPushNotificationConfigurations() built its URL as a plain string with no query parameters at all. The pageSize and pageToken fields on ListTaskPushNotificationConfigsParams were ignored, making pagination impossible. Fix: - Add statusTimestampAfter to buildListTasksQueryString(), formatted as ISO-8601 and URL-encoded (same pattern as existing string fields). - Extract buildListPushNotificationConfigsQueryString() for the push notification configs method and append the query string to the URL. - Add regression tests for both bugs using MockServer; each test asserts the query parameter is present in the outbound request. This fixes a2aproject#1233

This should be URLEncoded
Three issues identified in review by @ehsavoie: 1. listTasks proto builder did not set statusTimestampAfter. Interceptors (auth, tracing) receive the builder before the REST URL is built, so missing fields there are invisible to the interceptor chain. Added the Timestamp conversion using getEpochSecond()/getNano(). 2. listTaskPushNotificationConfigurations proto builder set only taskId. pageSize and pageToken were never set, making pagination invisible to interceptors. Added the two missing fields. 3. status enum value in buildListTasksQueryString was appended raw without URL-encoding. Applied URLEncoder.encode() for consistency with all other string parameters in the same method. Added two regression tests using a capturing ClientCallInterceptor to assert the proto builder carries the correct fields before the HTTP request is sent. This fixes a2aproject#1233

Thank you @ehsavoie — all three points addressed in the latest commit (e95a10a):

What this fixes
Two query parameters were silently dropped by the REST transport client, making server-side features unreachable from Java.
Bug 1 —
listTasksdropsstatusTimestampAfterbuildListTasksQueryString()handles every field inListTasksParamsexceptstatusTimestampAfter. The field was added to the record after the query builder was written and was never included. Every call toGET /tasksfrom the Java client omitted the timestamp filter entirely, so the server always returned all tasks regardless of when they were last updated.Bug 2 —
listTaskPushNotificationConfigurationsdropspageSizeandpageTokenThe URL was built as a plain string with no query parameters at all. The
pageSizeandpageTokenfields onListTaskPushNotificationConfigsParamswere never appended, making pagination impossible for push notification configs.What changed
statusTimestampAftertobuildListTasksQueryString(), formatted as ISO-8601 and URL-encoded (same pattern as existing string fields).buildListPushNotificationConfigsQueryString()for the push notification configs method and updatedlistTaskPushNotificationConfigurations()to append the query string to the URL.Fixes #1233
