Description

bug needs attention

How to reproduce:

  • Use gpt-6-astra in GitHub Copilot Chat extension. Make sure gpt-6-astra is from Microsoft Foundry via Foundry Toolkit
  • chat hello world

The solution is in the error log, but because model provided from Microsoft Foundry via Foundry Toolkit have no .json to edit, I cannot fix it myself. Would you mind making models provided from Microsoft Foundry via Foundry Toolkit to have a .json configuration file? Thank you
