Deep Research PDF export fails on ChatGPT Web

Hi OpenAI team,

I’m encountering an issue when using the Deep Research feature in ChatGPT Web.

After a Deep Research report is generated, I click Export → PDF, but the export fails. In DevTools, the request appears to go through the MCP endpoint and returns:

{"detail":"Failed to export document"}

Environment

• Product: ChatGPT Web
• Feature: Deep Research
• Action: Export report as PDF
• Browser: Chrome on Windows
• Language/UI locale: zh-CN
• Plan: Pro
• Endpoint observed in DevTools:
  • POST https://chatgpt.com/backend-api/ecosystem/call_mcp

Request details

The failing request body looks like this, with sensitive values redacted:

{
  "app_uri": "connectors://connector_openai_deep_research",
  "tool_name": "export",
  "conversation_id": "[REDACTED]",
  "message_id": "[REDACTED]",
  "tool_input": {
    "session_id": "[REDACTED]",
    "report_message_id": "[REDACTED]",
    "export_type": "pdf"
  }
}

The response is:

{
  "detail": "Failed to export document"
}

Expected behavior

The Deep Research report should export successfully as a PDF.

Actual behavior

PDF export fails with:

{"detail":"Failed to export document"}

Steps to reproduce

1. Open ChatGPT Web.
2. Use Deep Research to generate a report.
3. Click the export option.
4. Select PDF.
5. The export request to /backend-api/ecosystem/call_mcp fails with Failed to export document.

Things I tried

• Retrying the export
• Refreshing the page
• Reopening the conversation

The issue still occurs.

Question

Is this a known issue with Deep Research PDF export / MCP export tooling?

Thanks.
