Actions4
Overview
The node interacts with an AI-powered podcast-style audio generation service. Specifically, the Wait for Completion operation under the Audio resource allows users to wait until a previously started audio generation task completes or fails. This is useful when you want to pause workflow execution until the audio content is fully generated and ready for further processing.
Typical use cases include:
- Waiting for long-running audio synthesis tasks to finish before downloading or using the audio.
- Automating workflows that depend on the completion of audio generation, such as publishing podcasts or sending notifications.
- Polling the status of asynchronous audio generation jobs without manual intervention.
For example, after initiating an audio generation task, you can use this node operation to wait up to a specified timeout period, checking periodically at defined intervals whether the task has completed successfully or failed.
Properties
| Name | Meaning |
|---|---|
| Task ID | The unique identifier of the audio generation task to monitor. |
| Timeout (Seconds) | Maximum time in seconds to wait for the task to complete before timing out (default 3600). |
| Poll Interval (Seconds) | Time in seconds between each status check request (default 30). |
Output
The output JSON contains the full response from the audio generation service's task status endpoint. When the task completes successfully, the output includes details about the completed audio generation task, such as its status and any associated metadata.
If the task fails, the output will contain error information describing the failure reason.
No binary data is output by this operation; it strictly returns JSON status information about the audio generation task.
Dependencies
- Requires an API key credential for the external AI podcast audio generation service.
- The node uses authenticated HTTP requests to the service's REST API endpoints.
- Proper configuration of the API base URL and authentication credentials within n8n is necessary.
Troubleshooting
- Timeout Errors: If the task does not complete within the specified timeout, the node throws a timeout error. Increase the timeout value if your audio generation tasks typically take longer.
- Task Failure: If the audio generation task fails, the node throws an error with the failure message returned by the service. Check the error details to understand the cause (e.g., invalid input, service issues).
- Invalid Task ID: Providing an incorrect or expired task ID will result in errors or no progress. Ensure the task ID comes directly from a successful audio generation initiation.
- API Authentication Issues: Errors related to authentication indicate misconfigured or missing API credentials. Verify that the API key credential is correctly set up in n8n.
