FATAL: API error in Wayland stand alone app.

[mclovin22117]

The script is catching the real error in the background, hiding it, and just spitting out that generic "FATAL" fallback message.
It is being fixed.

[abhinavgautam01]

found it, confirmed in system_enhancer.py. The FATAL string is hardcoded at the end of try_transform_text():

return "\n⚠️ FATAL: ALL configured APIs failed to process the request."

This is returned only if every provider in PROVIDER_ORDER either isn't in AI_CLIENTS (no key configured) or raises an exception during call_llm_api. The actual exception is printed via:

print(f"❌ Failed using {provider_name}: {e.__class__.__name__} - {e}. Attempting fallback...")

but that only goes to stdout in the terminal, stringcast_ui.py's AIWorker never receives it, so the GUI just shows the generic fallback with zero diagnostic info.

Most likely root cause

1. Missing/empty .env — load_dotenv() in system_enhancer.py looks for .env in the current working directory. If setup_environment.sh is run from a different directory, or there's no .env with GEMINI_API_KEY / OPENAI_API_KEY, both clients fail to initialize and AI_CLIENTS ends up empty.
2. If keys are set but invalid/expired, genai.GenerativeModel(...).generate_content() or client.chat.completions.create() will raise (auth error, quota, etc.), both caught silently.

Suggested fix

• Add a startup log of configured providers in system_enhancer.py:

  print(f"Configured providers: {list(AI_CLIENTS.keys())}")

• Propagate the real error into the returned string instead of swallowing it:

  errors = []
  for provider_name in PROVIDER_ORDER:
      if provider_name not in AI_CLIENTS:
          errors.append(f"{provider_name}: not configured")
          continue
      try:
          return call_llm_api(provider_name, text_to_enhance, system_instruction)
      except Exception as e:
          errors.append(f"{provider_name}: {e.__class__.__name__} - {e}")
  
  return "\n⚠️ FATAL: All APIs failed.\n" + "\n".join(errors)

• setup_environment.sh should check for a .env file and warn (or scaffold a template) if it's missing — right now it silently proceeds even with zero keys configured.

Question

@mclovin22117 — can you confirm whether a .env file exists in the project root with valid GEMINI_API_KEY / OPENAI_API_KEY? My bet is that's the actual issue, and it's entirely separate from the Wayland PoC... this PyQt app (stringcast_ui.py / system_enhancer.py) doesn't touch wayland_listener.py at all.

[mclovin22117]

Yes. That was the issue sort of. I have patched the fix and will push the code in a while.

[mclovin22117]

The issue has been resolved.
