Overview
This node integrates with the etiquetas.io platform, specifically focusing on managing devices and their associated data. The "Ver Imagem Preview ESL" operation under the Device resource allows users to retrieve a preview image of an Electronic Shelf Label (ESL) bound to a specific device ID. This is useful in retail or inventory management scenarios where visual confirmation of label bindings is needed.
Practical examples include:
- Fetching the current preview image of an ESL for a given device to verify correct label assignment.
- Displaying the ESL image in a dashboard or application interface for quick reference.
Properties
| Name | Meaning |
|---|---|
| ID | The unique identifier of the device whose ESL preview image you want to view. |
| outputField | The name of the field in the output JSON where the retrieved image data will be stored. |
Output
The node outputs JSON data containing the ESL preview image associated with the specified device ID. The exact structure depends on the API response but typically includes image data or a URL pointing to the preview image.
If the outputField property is set to "data", the image data or its reference will be accessible under that key in the output JSON.
No binary data output is indicated by the source code; the image is likely provided as a URL or base64 string within the JSON.
Dependencies
- Requires an API key credential for etiquetas.io to authenticate requests.
- Needs network access to etiquetas.io services.
- No additional environment variables are explicitly required beyond the API authentication.
Troubleshooting
- Invalid or missing device ID: Ensure the device ID provided exists and is correctly formatted; otherwise, the API may return errors or empty results.
- Authentication errors: Verify that the API key credential is valid and has necessary permissions.
- Network issues: Confirm connectivity to etiquetas.io endpoints.
- Output field conflicts: Make sure the
outputFieldname does not clash with other output properties to avoid overwriting data.
Common error messages might relate to unauthorized access, invalid parameters, or resource not found. Resolving these involves checking credentials, input values, and device existence.
