error getting custom model packs: %v

Error message

error getting custom model packs: %v

What it means

This error wraps a failure from api.Client.ListModelPacks() in set_model's parallel fetch (one of three goroutines feeding errCh). The *shared.ApiError Msg is interpolated into 'error getting custom model packs: %s'. It means the custom model packs listing failed, so the model selection flow cannot proceed.

Solutions

1. Re-authenticate to refresh the API token
2. Check the err.Msg embedded in the output for the HTTP status and message
3. Verify network/proxy connectivity to the API host
4. Confirm your org/account has access to custom model packs

Example fix

// before
errCh <- fmt.Errorf("error getting custom model packs: %v", apiErr.Msg)
// after
errCh <- fmt.Errorf("error getting custom model packs (status %d): %v", apiErr.Status, apiErr.Msg)

// pre-flight: authenticated client with reachable API
if api.Client == nil {
	return fmt.Errorf("client not initialized: authenticate first")
}
if err := api.Client.HealthCheck(); err != nil {
	return fmt.Errorf("API unreachable: %w", err)
}

func isApiErr(err error) (*shared.ApiError, bool) {
	ae, ok := err.(*shared.ApiError)
	return ae, ok
}

packs, err := retry(3, backoff, func() ([]ModelPack, error) {
	return api.Client.ListModelPacks()
})
if err != nil {
	if ae, ok := err.(*shared.ApiError); ok && ae.Status == 401 {
		return reauth()
	}
	return fmt.Errorf("error getting custom model packs: %w", err)
}

When it happens

Trigger: ListModelPacks() returning non-nil *shared.ApiError: invalid or expired API credentials, network failure, or the server rejecting the request (403 for lacking model-pack access, 500 server error).

Common situations: Token expiry during long sessions; org plan without custom model packs enabled; API outage; firewall/proxy blocking the endpoint.
