An error occurred while downloading the model

Error message

An error occurred while downloading the model

What it means

Lemonade model download UI, mirroring the DMR one: after a size confirmation, LemonadeUtils.downloadModel(modelId, basePath, progressCallback) runs; success:false throws the util's error or this generic fallback, surfaced as a toast while console.error records the details.

Solutions

1. Verify the Lemonade server is up, then retry the download
2. Check console/network for the exact failure (HTTP status from Lemonade or HF)
3. Ensure disk space for the advertised file size and a stable connection (disable VPN/proxy if it blocks HF)
4. Confirm the model id is valid by refreshing the Lemonade catalog list

const serverUp = await LemonadeUtils.healthCheck?.();
if (!serverUp) return showToast("Start the Lemonade server before downloading", "error");
if (!hasDiskSpace(fileSize)) return showToast("Not enough disk space for this model", "error");

catch (e) {
  console.error("Error downloading model:", e);
  showToast(e.message, "error", { clear: true });
  if (/network|fetch|ECONN/i.test(e.message)) offerRetry(handleDownload);
}

When it happens

Trigger: Lemonade server down or unreachable; Hugging Face download failure (network/proxy, rate limit, model id unavailable); disk space insufficient; basePath invalid; progress stream aborted mid-download.

Common situations: Lemonade not started before clicking download; corporate proxy blocking huggingface.co; disk full; model id pulled from a stale list; long download interrupted by machine sleep.
