GitHub Copilot Chat Error: HydraFusion has no executable constituent after applying the allowed-model policy

Hi everyone,

I’m currently experiencing an issue with GitHub Copilot Chat in VS Code and I’m hoping someone can help me understand what is causing it.

Whenever I try to use Copilot Chat, I receive the following error:

Error: (query) Execution failed: HydraFusion has no executable constituent after applying the allowed-model policy > > Try Again

I also noticed the following information in the GitHub Copilot Chat extension:

GitHub Copilot Chat, Built in
Activation: Activated by onStartupFinished event
Copilot Usage:
Uncaught Errors (1):

Task API request failed: 403

The Copilot Chat extension itself appears to be activated successfully, but the chat requests are failing with a 403 error.

I have already tried clicking Try Again, but the same error continues to appear.

Has anyone experienced this HydraFusion / allowed-model policy error before?

I would appreciate any suggestions on how to fix it or whether this could be related to my Copilot account, model access, subscription, or VS Code configuration.

Thanks!
