## TL;DR

API-level failures like bad model name, rate limits, or quota exceeded are returned in the response instead of raised, so always check response.status_code against HTTPStatus.OK and read response.code and response.message. Missing required arguments such as no model, no messages or prompt, or no API key raise a DashScopeException subclass immediately.

## The error

```text
API errors come back in the response, not as exceptions
```

## Fix

1. API-level failures like bad model name, rate limits, or quota exceeded are returned in the response instead of raised, so always check response.status_code against HTTPStatus.OK and read response.code and response.message.
   Expected: You see the expected output instead of the problem.
2. Re-run the original operation and confirm the error is gone.
   Expected: no error, normal output.

## When to use

- You hit this exact error with DashScope Python SDK.
- The symptom matches: API errors come back in the response, not as exceptions.

## When NOT to use

- A different error message from DashScope Python SDK; the cause here is specific to this error.
- Unrelated DashScope Python SDK issues (different feature, different failure).
- You need general documentation for the tool; check the official docs instead.

## Variant phrasings

### API errors come back in the response, not as exceptions

## Why it happens

The DashScope Python SDK only raises for local input problems. API-side failures land in the response object, so a missing status check silently swallows errors.

## Edge cases

- If your error message differs even slightly, this is probably a different issue; search the exact text.
- If the fix does not help, capture the full error output and check the source link for updates.
