PROVIDER_UNDETERMINED

PROVIDER_UNDETERMINED

Error message

Could not determine the provider for model ID "${modelId}".

What it means

A safeguard inside setModel(): after internal lookup and custom-model handling, the resolved provider was still null when the code reached the configuration-update step. This should be unreachable via normal flags and usually indicates an internal inconsistency — a model matched internally without a provider field, or a custom-hint path that failed to set the provider.

Solutions

1. Re-run the command with an explicit provider flag (--openrouter/--ollama/--bedrock/...) so determinedProvider is set directly from the hint.
2. Reinstall task-master to rule out a corrupted/forked models.js or mismatched internal model list.
3. Update to the latest version; if it persists, report the model id + role combination as a bug since this path is a defensive fallback.

Example fix

// before (internal entry lacks provider — patched map)
'my-model': { maxTokens: 128000 }
// after
'my-model': { maxTokens: 128000, provider: 'openai-compatible' }

// Ensure the target model resolves to a provider before calling setModel
const cfg = JSON.parse(fs.readFileSync('.taskmaster/config.json', 'utf8'));
if (!cfg.models?.[role]) console.warn(`Role "${role}" missing from config — provider resolution may fail`);

const res = await setModel(modelId, role, projectRoot, options);
if (!res.success && res.error?.code === 'PROVIDER_UNDETERMINED') {
  // safeguard path: retry with an explicit provider hint
  return setModel(modelId, role, projectRoot, { providerHint: 'openrouter' });
}

When it happens

Trigger: setModel(modelId, role, root) where providerHint resolves but is later dropped/overwritten, or where an internally-known model entry has no provider property; custom flows that bypass the providerHint assignment; race/pathologies from monkey-patched or outdated config modules.

Common situations: Patched or forked task-master code where the internal MODEL_MAP entries lost their provider field; mixing versions where config helpers (getConfig/writeConfig) come from a different install; unusual provider aliases not covered by the hint mapping.
