DurableTasks: Warning when workflow started outside of the SDK context #1378
Description
Expected Behavior
Not sure, but at least the warning should be more clear about why it is failing on the durable task side.
Actual Behavior
You start a Java application with some workflows registered, but instead of using the application to create a new instance, you send a curl request to the Dapr API to start a new workflow instance.
In that situation, because the App doesn't have started the workflow and probably don't have the context, durable task framework prints this warning:
2025-05-16T15:28:17.408+01:00 WARN 20378 --- [pool-3-thread-1] io.dapr.durabletask : The orchestrator failed with an unhandled exception: java.lang.NullPointerException: Cannot invoke "io.dapr.durabletask.TaskOrchestrationFactory.create()" because "factory" is null

After further inspection, the Warning only appears if you call a Workflow that is not registered or use the wrong name of the workflow. I think the only action item here is to refine the Warning message on the durable-task.

One thing to try here is to add a log line here: https://github.com/dapr/durabletask-java/blob/main/client/src/main/java/io/dapr/durabletask/TaskOrchestrationExecutor.java#L62 to evaluate if the context is null and mention that there is no context associated with the workflow that you are trying to execute, because it doesn't exist. But this is all handled in the SDK code.
As mentioned before, this will not happen if all the requests come from an application that is using the SDK

@salaboy I can look at this.
