error fetching custom models: %v

Error message

error fetching custom models: %v

What it means

GetServerModelsInput fetches custom models/providers via three goroutines communicating over an errCh; if any of the three results carries a non-nil error it aborts with 'error fetching custom models: %v'. It aggregates a failure in retrieving server-side custom model configuration.

Solutions

1. Read the wrapped inner error (err.Msg) for the failing fetch's root cause
2. Retry — transient server/network errors often clear on re-run (SyncCustomModels retries the flow)
3. Verify authentication and that the models endpoint is reachable
4. Review server-side custom models/providers for malformed entries and remove/fix them

Example fix

// before: first error aborts everything
for i := 0; i < 3; i++ {
    err := <-errCh
    if err != nil {
        return nil, fmt.Errorf("error fetching custom models: %v", err.Msg)
    }
}
// after: caller retries on failure
input, err := GetServerModelsInput(...)
if err != nil {
    return retry(3, func() error { _, err = GetServerModelsInput(...); return err })
}

if err := pingModelsEndpoint(ctx); err != nil {
    return fmt.Errorf("models endpoint unreachable: %w", err)
}

input, err := GetServerModelsInput(...)
if err != nil && strings.Contains(err.Error(), "error fetching custom models") {
    // bounded retry for transient server/network failures
    for i := 0; i < 3; i++ {
        if input, err = GetServerModelsInput(...); err == nil {
            break
        }
        time.Sleep(backoff(i))
    }
}

When it happens

Trigger: Any of the 3 parallel fetches (custom models, custom providers, or the third fetch) pushes an error onto errCh — e.g. server API call fails, auth error, or response parse failure while syncing custom models.

Common situations: API/server outage or network error while loading custom models; invalid API key; custom provider config on the server is malformed and fails to deserialize; timeout on the models endpoint.
