carloea2 opened a new issue, #8094: URL: https://github.com/apache/texera/issues/8094
## What happened? Root cause: the WebSocket handler checks that a workflow is attached, then dereferences an execution service that can still be null. Before: a workflow is attached but execution has not started, then ModifyLogicRequest throws a NullPointerException. Expected: the handler reports that workflow execution is not initialized and sends a WorkflowErrorEvent. ## How to reproduce? 1. Attach a WebSocket session to a workflow without starting execution. 2. Send a ModifyLogicRequest frame. 3. Observe the NullPointerException. A regression test against commit caeb27ea54 reproduced this with 15 passing tests and 1 failing test. ## Version or branch 1.3.0-incubating-SNAPSHOT on main ## Commit hash caeb27ea54 ## Browsers Not browser specific. ## Relevant log output java.lang.NullPointerException -- This is an automated message from the Apache Git Service.
