Model selector crashes: 'dict' object has no attribute 'lower'

[nickeysun]

Summary

Model selector dropdown crashes with 'dict' object has no attribute 'lower'.

Steps to Reproduce

1. Open Hermes Desktop on macOS.
2. Click the model selector in the bottom input bar (Step 3.7 Flash:Free ...).
3. The dropdown panel shows an error message instead of the model list:
   'dict' object has no attribute 'lower'.

Expected Behavior

The model list should load and allow switching models.

Actual Behavior

The dropdown shows an error stub and the model list cannot be switched.

Environment

• OS: macOS (Apple Silicon)
• Version: # v0.18.0 (ed41237)

Notes

• Issue appears to be in the model list rendering code.
• model_catalog.enabled is true in config.
• Config file ( model / providers / model_catalog ) looks valid in ~/.hermes/config.yaml.
• This prevents normal model switching in the desktop app UI.
• Use-case workaround: falling back to other clients while this is fixed.

Related: #33372 and #55770 (both open) already fix this exact crash. The model picker's build_models_payload / list_authenticated_providers in hermes_cli/model_switch.py appends list-of-{id,label} dict entries from provider config verbatim, then a downstream m.lower() blows up on the dict. #33372 is the broader/earlier fix (normalizes both branches + tests); #55770 is a narrower inline fix. Keeping this open as the bug report so a maintainer can pick a fix PR.

Thanks for the clear desktop reproduction. This is an automated hermes-sweeper review; current main already implements the required normalization.

• fc18d15f4 (fix: preserve static custom provider models) added hermes_cli/model_switch.py:_declared_model_ids() at line 55, which converts list-of-{id: ...} / {name: ...} entries to validated string IDs.
• The affected providers: picker construction now uses that helper at hermes_cli/model_switch.py:2046; the equivalent grouped custom-provider path uses it at line 2274.
• Desktop's model.options RPC calls the shared build_models_payload() path in tui_gateway/server.py:12951.
• Regression coverage for list-of-dict model declarations is in tests/hermes_cli/test_inventory.py:65.
• The fix shipped in v2026.7.7.

Closing as implemented on main.
