Android ChatGPT app error after before tools/call

In addition to @LarisaHaster's great response, can you try a minimal static component resource on the same app/tool first?

No JS bundle, no external assets, no OAuth, no redirects, no custom domain logic, just a tiny inline/static widget and see whether Android reaches tools/call.

Given your logs (initialize, tools/list, resources/list, resources/read all 200), the failure likely happens during widget render/bootstrap inside the Android client before the tool invocation path.

Also useful to inspect:

• exact resources/read payload + response headers
• tool descriptor _meta (especially openai/outputTemplate, ui.resourceUri, widget accessibility flags)
• CSP + widget domain config
• Android logcat / WebView console errors
• whether the widget depends on:
  • browser-only APIs
  • third-party cookies/storage
  • redirects
  • cross-origin assets
  • service workers
  • dynamic imports/module loading
  • mixed-content HTTP assets

If the minimal component works, it points more toward CSP, asset loading, Android WebView compatibility, auth/session handling, or frontend JS crashing before the tool call.

If even the minimal widget fails before tools/call, that’s much stronger evidence of an Android ChatGPT client/App SDK regression rather than your server/tool handler.

Feel free to open a support ticket to support@openai.com with request_IDs and any details that would be helpful as mentioned above.
