Failed to create video task: ${createResponse.base_resp?.sta

Error message

Failed to create video task: ${createResponse.base_resp?.status_msg || 'Unknown error'}

What it means

Thrown by the MiniMax text-to-video (t2v) operation after POST /video_generation when createResponse.base_resp.status_code is non-zero. Identical pattern to the i2v create failure (error 868) but for the text-only video path; status_msg is mirrored into the error.

Solutions

Read status_msg in the error for the upstream reason.
Simplify/soften the prompt and retry.
Verify model and resolution are supported for the account tier.
Check video-generation credits and API key scopes.
Drop optional fields (prompt_optimizer) to isolate a rejected parameter.

Defensive patterns

Strategy: validation

Validate before calling

const SUPPORTED_T2V_MODELS = ['video-01', 'video-01-live2d'] as const;
const SUPPORTED_T2V_RESOLUTIONS = ['720p', '1080p'] as const;
function validateT2vInput(opts: { prompt?: string; model?: string; resolution?: string; promptOptimizer?: boolean }) {
  if (!opts.prompt || opts.prompt.trim().length === 0) return 'prompt is required for t2v';
  if (opts.prompt.length > 4000) return `prompt length ${opts.prompt.length} likely exceeds the limit`;
  if (opts.model && !SUPPORTED_T2V_MODELS.includes(opts.model as never)) return `model '${opts.model}' is not recognized for t2v`;
  if (opts.resolution && !SUPPORTED_T2V_RESOLUTIONS.includes(opts.resolution as never)) return `resolution '${opts.resolution}' is not recognized`;
  return null;
}

Type guard

function isT2vCreateSuccess(r: unknown): r is { base_resp: { status_code: 0 }; task_id: string } {
  const b = (r as { base_resp?: { status_code?: number } })?.base_resp;
  return !!b && b.status_code === 0 && typeof (r as { task_id?: unknown })?.task_id === 'string';
}

Try / catch

const createResponse = (await apiRequest.call(this, 'POST', '/video_generation', { body })) as VideoGenerationResponse;
if (createResponse.base_resp?.status_code !== 0) {
  throw new NodeOperationError(
    this.getNode(),
    `Failed to create video task: ${createResponse.base_resp?.status_msg || 'Unknown error'}`,
  );
}

Prevention

Sanitize prompts to avoid content-moderation rejection before sending.
Validate model/resolution against the account tier before deploying.
Drop optional prompt_optimizer to isolate a rejected parameter if failures recur.
Monitor video-generation credits and alert before exhaustion.

When it happens

Trigger: Prompt triggers content moderation; model/resolution/prompt_optimizer combination unsupported; account out of video credits; API key lacks video permission; prompt exceeds length limit.

Common situations: Disallowed prompt content; resolution not enabled for tier; quota exhausted; rotated API key without video scope.
