how to handle 400 response in custom code
To handle a 400 response in custom code, you can use the validateStatus property when making an HTTP request with axios. This allows you to process the error data instead of throwing an error. Here’s an example: ```
import { axios } from “@pipedream/platform”; export default defineComponent({ async run({ steps, $ }) { const resp = await axios($, { url: “https://httpstat.us/400”, validateStatus: () => true, // will not throw error when axios gets a 400+ status code (the default behavior) }); if (resp.status >= 400) { this.debug = resp; throw new Error(JSON.stringify(resp.data)); // This can be modified to throw any error you’d like } return resp; } });
how to make a helper object of functions that can resused accross my workflows
To create a helper object with reusable functions, you can use a Pipedream code step to define the helper object and its functions. Then, you can use these functions in other steps within the same workflow. However, to reuse the helper object across multiple workflows, you’ll need to create an API endpoint that returns the helper functions, and call that API from your workflows. Here’s an example of defining a helper object with functions in a code step: export default defineComponent({ async run({ steps, $ }) { const helper = { add: (a, b) => a + b, multiply: (a, b) => a * b, }; // Use the helper functions in your workflow const sum = helper.add(3, 4); const product = helper.multiply(3, 4); return { sum, product }; }, }); To reuse this helper object across multiple workflows, you can create an API endpoint (using a service like AWS Lambda, Google Cloud Functions, or your own server) that returns the helper functions. Then, call that API from your workflows using the axios package. Keep in mind that you’ll need to serialize and deserialize the functions when sending them over the network, as they cannot be directly transmitted as JSON. You can use toString() to serialize a function and eval() to deserialize it, but be cautious with eval() as it can introduce security risks if not used carefully.
can you help with custom code to exit workflow early if a condition is met
Certainly! To exit a workflow early based on a condition, you can use the $.end() method in a custom code step. Here’s an example: export default defineComponent({ async run({ steps, $ }) { const condition = true; // Replace this with your actual condition if (condition) { console.log("Condition met, exiting workflow early"); return $.end("Exiting workflow early due to condition"); } // Your remaining workflow steps will execute if the condition is not met }, }); In this example, if the condition is true, the workflow will exit early and log a message. Replace the condition with your actual condition to control when the workflow should exit early.
how to exit as well as send http response
To exit a workflow and send an HTTP response, you can use the “Return HTTP Response” action from the HTTP / Webhook app. Here’s how to set it up: 1. Search for the HTTP / Webhook app from the step menu. 2. Select the “Return HTTP Response” action. 3. Set the desired Response Status Code, Response Headers, and Response Body. Before this action, you can use a custom code step to check your condition and decide whether to exit the workflow or continue. If the condition is met, the workflow will proceed to the “Return HTTP Response” action and send the response. If you need more assistance, please let me know.
how to send htpp response first and then exit
In Pipedream, you cannot send an HTTP response first and then exit the workflow within the same step. However, you can send an HTTP response using the “Return HTTP Response” action and then exit the workflow in a subsequent code step based on a condition. Here’s an example: 1. Add the “Return HTTP Response” action from the HTTP / Webhook app. 2. Set the desired Response Status Code, Response Headers, and Response Body. 3. Add a custom code step after the “Return HTTP Response” action. In the custom code step, you can check your condition and exit the workflow using $.end() if the condition is met: export default defineComponent({ async run({ steps, $ }) { const condition = true; // Replace this with your actual condition if (condition) { console.log("Condition met, exiting workflow"); return $.end("Exiting workflow due to condition"); } // Your remaining workflow steps will execute if the condition is not met }, }); In this example, if the condition is true, the workflow will exit after sending the HTTP response. Replace the condition with your actual condition to control when the workflow should exit.
