Overview

This node, named "jimeng Node," is designed to interact with a service related to image generation and management. Specifically, for the resource "图片生成" (Image Generation) and operation "获取图片状态" (Get Image Status), it retrieves the status of an image based on a provided history ID. This functionality is useful in workflows where you need to track or verify the processing state of generated images, such as confirming completion before further processing or notifying users about progress.

Practical examples include:

  • Checking if an image generation task has completed successfully.
  • Polling the status of an image generation job in asynchronous workflows.
  • Integrating image status checks into larger automation pipelines that depend on image availability.

Properties

Name Meaning
historyId The unique identifier representing the history or record of the image generation task whose status you want to retrieve.

Output

The node outputs JSON data representing the status information of the requested image generation task. Each output item corresponds to one input item and contains fields describing the current state of the image associated with the given historyId.

If the node supports binary data output (not explicitly shown in the code snippet), it would typically represent the actual image file or related binary content. However, based on the provided code and context, the primary output is JSON-formatted status information.

Dependencies

  • Requires an API key credential for authentication with the external image generation service.
  • Depends on the external service's API endpoint corresponding to the "获取图片状态" operation.
  • Uses the n8n workflow helpers and error handling utilities.
  • The node relies on a resource factory (ResourceFactory) to dynamically build and call the appropriate API method based on the selected resource and operation.

Troubleshooting

  • Common issues:

    • Providing an invalid or empty historyId will likely result in errors or no meaningful status returned.
    • Network or authentication failures can cause the node to throw errors.
    • If the external service changes its API or deprecates the called method, the node may fail with an "unimplemented method" error.

  • Error messages:

    • "未实现方法: 图片生成.获取图片状态" ("Unimplemented method: 图片生成.获取图片状态"): Indicates that the requested resource-operation combination is not implemented in the node. Verify that the resource and operation names are correct and supported.
    • Errors containing "errorMessage" and stack traces are logged; enabling "Continue On Fail" allows the workflow to proceed despite individual item errors.

  • Resolution tips:

    • Ensure the historyId is correctly set and valid.
    • Confirm that the API credentials are properly configured and have necessary permissions.
    • Check network connectivity and API endpoint availability.
    • Update the node or plugin if the external API has changed.
