Copilot Agent "An external link was removed to protect your privacy" Error

Hi everyone,

I’m using the paid version of Microsoft Copilot and have encountered an issue with a Copilot Agent I created. I’d appreciate any help or suggestions from the community.

Use Case:
The agent is designed to generate a downloadable Word document report based on user inputs (files and prompts) and a curated knowledge base. The knowledge base includes folders with previously developed reports, templates, and other relevant documentation.

What’s Working:

• The agent correctly uses the knowledge base and user prompts to generate accurate report content.
• The logic and flow of the agent are functioning as expected.

The Problem:
When the agent attempts to generate the downloadable Word document, it fails and returns the message:

"An external link was removed to protect your privacy."

However, when I use the same prompts and files directly in the Copilot chat interface, the Word document is generated and is downloadable without any issues.

What I Need Help With:

• Has anyone else experienced this issue with Copilot Agents?
• Is this a known limitation or a configuration/privacy setting I might be missing?
• Any workarounds or documentation that could help?

Thanks in advance for your help!
