Can you provide more details as requested in the bug template? Are you using the app or the extension? Which version? Which platform?

Do you suspect that this is a regression? Has it worked for you previously?

Hi there,

Thank you for your reply and sorry for not providing enough details initially. Here are the complete details as requested:

  • Usage scenario: I'm using the desktop app (not the extension)
  • App version: 60208.1016 (571)
  • Operating platform: macOS 26.2
  • Issue occurrence: The JSON error message pops up when I attempt to start a chat. This problem first appeared on my third attempt to use the chat function after installing the app.
  • Troubleshooting attempts: I have tried logging out of my account and logging back in, but the issue still remains unresolved.

I haven't used this feature successfully before, so I'm not sure if it's a regression issue. Please let me know if you need any additional information (such as error logs or screen recordings) to investigate this problem further.

Thanks for your help!

It appears that you've configured an LLM proxy either using the base_url config key in a custom model provider or an OPENAI_BASE_URL environment variable. It's pointing to https://www.88code.org/openai/v1/responses, which I assume is a proxy of some sort. It's returning a 400 error.
