Signals Notebook: GET /entities/{eid}/pdf returns 404 error

Description

When using the GET /entities/{eid}/pdf API endpoint, you may encounter the following error for certain experiments:

Potential Causes

1. Experiment Metadata or Configuration Issues
   • The experiment may contain incomplete, corrupted, or unsupported metadata that prevents PDF generation.
   • Review the experiment content, structure, and configuration for inconsistencies.
2. PDF Generation Service Limitations
   • Certain experiment states or data conditions may prevent the PDF from being generated successfully.
   • If possible, make a minor edit to the experiment, save the changes, revert the edit if necessary, and then retry the export using the GET /entities/{eid}/pdf endpoint.
3. Permissions or Access Restrictions
   • The requesting user may not have sufficient permissions to generate or access the PDF.
   • Verify that the experiment is accessible, and try generating a PDF from the user interface to determine whether the issue is API-specific.

Workaround

If the synchronous PDF export endpoint fails, use the asynchronous PDF export workflow instead:

1. Export the entity asynchronously using the PUT /entities/export/pdf endpoint. The request body can be empty.
2. Retrieve the generated PDF using the returned file ID and the GET /entities/export/pdf/{fileid} endpoint.
