I have an rss trigger that checks for new events every time and sends a message to a social network after doing a “end_based_on_condition” check. After doing this check the flow can ends and the event, if it meets that condition, on the next scan, is not taken into consideration. How do I make the flow finish so that the event if it ends on “end_based_on_condition” is reconsidered on the next scan?
To address your requirement of reconsidering an event in the next scan after a workflow ends based on a condition, you can utilize a data store to keep track of events that have been processed and those that need to be reconsidered. Here’s a step-by-step approach using Node.js: 1. Create a Data Store to Track Events: Use a data store to keep a record of events that have been processed. If an event meets the condition to end the workflow early, you can mark it in the data store as needing reconsideration. 2. Check the Data Store Before Processing an Event: At the beginning of your workflow, check if the current event is marked in the data store as needing reconsideration. If it is, proceed with processing. If not, perform your “end_based_on_condition” check. 3. Mark Events Needing Reconsideration: If an event meets your condition to end the workflow early but should be reconsidered in the next scan, mark it accordingly in the data store. Here’s an example of how you might implement this logic: export default defineComponent({ props: { data: { type: "data_store" }, }, async run({ steps, $ }) { const eventId = steps.trigger.event.id; // Assuming your event has an ID const processedEvents = await this.data.get("processedEvents") || {}; // Check if the event was previously processed and needs reconsideration if (processedEvents[eventId] === "reconsider") { // Process the event as it needs reconsideration } else { // Perform your "end_based_on_condition" check const shouldEnd = someConditionCheck(); // Replace with your actual condition check if (shouldEnd) { // Mark the event for reconsideration and end the workflow processedEvents[eventId] = "reconsider"; await this.data.set("processedEvents", processedEvents); return $.flow.exit("Ending workflow based on condition, event marked for reconsideration."); } } // If the event is processed successfully, mark it as processed processedEvents[eventId] = "processed"; await this.data.set("processedEvents", processedEvents); // Continue with sending a message to a social network or other actions }, }); This code snippet assumes your events have a unique identifier (id) that you can use to track them. The `someCondition
Instead how can I stop the workflow brutally ?
To stop a workflow execution immediately and “brutally” as you’ve described, you can use the $.flow.exit() method within any code step in your workflow. This method ends the execution of the workflow immediately, ensuring that no remaining code in that step, and no code or destination steps below, will run for the current event. Here’s a basic example: export default defineComponent({ async run({ steps, $ }) { return $.flow.exit("Stopping workflow execution immediately."); }, }); This method allows you to exit the workflow early under any condition you define in your code. For more detailed scenarios and examples, you might want to check the documentation on ending a workflow early. If you’re looking to prevent the workflow from being triggered at all for a period, you can also throttle workflow execution by setting the concurrency limit to 0 in the workflow’s settings. This effectively pauses the workflow, as described in the concurrency and throttling documentation. Remember, using $.flow.exit() is a code-based solution for stopping the workflow during its execution, while adjusting the concurrency settings is a broader approach to controlling when your workflow runs.
it doesn’t stop brutally the workflow but ends the step and then stop the workflow
Based on your description, it sounds like you’re looking for a way to end a Pipedream workflow execution early, but in a manner that completes the current step before stopping the workflow entirely. In Pipedream, the $.flow.exit() method is used to exit a workflow early. When you call return $.flow.exit(), it ends the execution of the workflow immediately after the current step completes. No remaining code in that step, and no code or destination steps below, will run for the current event. Here’s an example of how you can use it: ```
export default defineComponent({ async run({ steps, $ }) { // Your code logic here // If a certain condition is met and you want to end the workflow early if (condition) { return $.flow.exit(“Optional exit message”); } // Code here will run if the condition is not met }, });
Instead how can I stop the workflow with an error ?
To stop a workflow with an error in a Python code step, you can simply raise an exception with a custom error message. This will halt the execution of the workflow immediately and log the error message. Here’s an example on how you can do it: ```
raise Exception(“Custom error message indicating the reason for stopping the workflow.”)

Instead how can I stop the workflow with an error ? Can you make an example
To stop a workflow with an error in Pipedream, you can throw an error within any code step. When you throw an error, the workflow execution will stop, and the error will be logged. Here’s an example of how you can do this: export default defineComponent({ async run({ steps, $ }) { // Your conditional logic here // For example, if a certain condition is met, throw an error if (true) { // Replace `true` with your actual condition throw new Error("Custom error message"); } // This code will not run if the condition above is met and the error is thrown console.log("This code will not run if the error is thrown"); }, }); In this example, replace true with your actual condition that determines whether to stop the workflow. The message "Custom error message" should also be replaced with a message that describes the reason for the error. This approach allows you to handle errors explicitly in your workflows, giving you control over when and why a workflow should stop executing due to an error.
