Getting "unhandled errors in a TaskGroup (1 sub-exception)" error when connecting/refreshing Development ChatGPT App

Hi there,

When trying to connect or refresh a development ChatGPT App using ChatGPT Apps SDK, it shows “unhandled errors in a TaskGroup (1 sub-exception)” error. Check different ChatGPT development Apps, they are the same.

Thanks in advanced to looking at this issue.

May be related but not recently: MCP Integration unhandled errors in a TaskGroup (1 sub-exception)
Anyone else hitting 424 / TaskGroup errors when creating a custom MCP connector?

Cheers,
Jake

Hello, I started seeing this error today - first when I refreshed an existing app, and then any time I tried to add a custom ChatGPT app. The app itself works just fine in inspector, and I don’t see any errors on my server.

When I inspect the network to see what is happening, I see a ‘424 Failed Dependency’ on a POST request to “backend-api/aip/connectors/mcp”
