Image generation failed: {response.code}, {response.message}

Error message

Image generation failed: {response.code}, {response.message}, status={response.status_code}

What it means

When DashScope returns a non-200 status_code, generate_image raises a RuntimeError embedding the provider's error code, message, and HTTP status — the authoritative provider-side failure signal.

Solutions

  1. Read response.code/response.message in the error to identify the cause
  2. Fix credentials or top up quota if 401/quota-related
  3. Back off and retry on rate-limit codes
  4. Rephrase the prompt if the code indicates content moderation

Example fix

// before
paths = gen.generate_image(prompt=p, model="wan2.7-image", size="9999*1")
// after
paths = gen.generate_image(prompt=p, model="wan2.7-image", size="1024*1024")
Defensive patterns

Strategy: try-catch

Validate before calling

if response.status_code != 200:
    if "Throttling" in str(response.code):
        time.sleep(backoff)
    elif "InvalidApiKey" in str(response.code):
        raise SystemExit("Fix DASHSCOPE_API_KEY")

Try / catch

try:
    paths = gen.generate_image(prompt=p)
except RuntimeError as e:
    if "status=429" in str(e) or "Throttling" in str(e):
        time.sleep(5)
        paths = gen.generate_image(prompt=p)
    else:
        raise

Prevention

When it happens

Trigger: Any non-200 DashScope response: invalid API key (401), throttling/rate limit, insufficient quota, invalid parameters, model access denied, content policy rejection.

Common situations: Exhausted daily quota; wrong API key for the region/endpoint; unsupported size/model combination; triggering moderation filters with a flagged prompt.
