Overview
The node provides a variety of no-code utility functions grouped by resource and operation categories. Specifically, for the PDF resource with the Count PDF Pages operation, it counts the number of pages in a given PDF file. This can be useful in workflows where you need to validate or process PDFs based on their length, such as splitting large documents, generating summaries, or automating document management tasks.
For example, you might use this node to:
- Automatically check how many pages a PDF report contains before deciding whether to archive or forward it.
- Validate uploaded contracts to ensure they meet page count requirements.
- Trigger different processing paths depending on the size of the PDF.
Properties
| Name | Meaning |
|---|---|
| Code Variables | Allows defining variables from code editor functions to be used within the node's execution context. Each variable has a name/ID and a value. |
| URL or Binary Data | Choose whether the PDF input is provided as a public URL or as binary data (buffer). |
| URL | The public URL of the PDF file to analyze (required if "URL" is selected above). |
| Binary Data | The buffer content of the PDF file (required if "Binary Data" is selected above). |
| Pages | (Optional) Specifies particular pages inside the PDF file; usage depends on operation context. |
Output
The node outputs JSON data representing the result of the requested operation. For the Count PDF Pages operation, the output JSON will include the total number of pages found in the PDF document.
If the node supports binary data output (not specifically for this operation), it would represent the processed PDF or related files in binary form.
Dependencies
- Requires an API key credential for authentication with the external service providing the PDF utilities.
- The node sends requests to an external API endpoint corresponding to the selected resource and operation.
- No additional environment variables are explicitly required beyond the API key credential.
Troubleshooting
- Common issues:
- Providing an invalid or inaccessible URL may cause errors when fetching the PDF.
- Supplying malformed or unsupported binary data buffers could lead to processing failures.
- Missing required properties like URL or buffer depending on the chosen input type.
- Error messages:
- Errors related to network access or file retrieval usually indicate URL problems or permission issues.
- Validation errors may occur if required parameters are missing or incorrectly formatted.
- Resolutions:
- Verify that the PDF URL is publicly accessible and correctly entered.
- Ensure binary data is properly encoded and passed.
- Double-check all required fields are filled according to the selected input type.
