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
- Open ChatGPT Web.
- Use Deep Research to generate a report.
- Click the export option.
- Select PDF.
- The export request to
/backend-api/ecosystem/call_mcpfails withFailed 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.
