Generation failed

Error message

Generation failed

What it means

Thrown by generateHeadless when the polling loop receives a terminal 'failed' status from provider.getStatus. If lastStatus.error is present its value is used as the message, otherwise the generic 'Generation failed' is thrown. This is the provider reporting that the image job itself failed, not a transport error.

Solutions

1. Read lastStatus.error from the logs to get the backend-specific failure reason and address it (free VRAM, fix workflow, adjust prompt).
2. Retry the generation after the backend recovers or with simpler parameters.
3. Validate prompt/resolution inputs before submission to avoid backend rejections.
4. For ComfyUI, verify the workflow template and referenced checkpoints are installed.

try {
  return await generateHeadless(params)
} catch (e) {
  const msg = errorMessageFrom(e) ?? ''
  if (/generation failed/i.test(msg) || /failed$/i.test(msg)) {
    return { error: `Image generation failed: ${msg}` }
  }
  throw e
}

When it happens

Trigger: The provider backend accepted the job and started it, but the generation later failed — e.g. model load error, out-of-memory on the GPU, invalid prompt/workflow, content filter rejection, or an internal backend exception surfaced through getStatus.error.

Common situations: ComfyUI ran out of VRAM mid-generation; the workflow JSON referenced a missing node/model; an API provider rejected the prompt for policy reasons; the model crashed; an invalid resolution was requested.
