HTTPClientError
Error message
status={resp.status}, body={body} What it means
request() treats any HTTP status >= 400 as an error: it reads the response body, stores an ErrorResponse, and raises HTTPClientException(HTTPClientError) embedding status and body. This centralizes upstream HTTP failure reporting.
Solutions
- Read the body in the exception message to identify the upstream cause and fix the request accordingly
- Handle 429 with backoff/retry, 401/403 by refreshing credentials
- Validate the request payload against the API schema before sending
Example fix
// before
resp = await client.request(payload) # raises on 500
// after
try:
resp = await client.request(payload)
except HTTPClientException as e:
if 'status=429' in str(e): await asyncio.sleep(backoff); retry()
else: raise Defensive patterns
Strategy: try-catch
Validate before calling
# pre-check payload schema and expected endpoint validate_payload_schema(payload) assert endpoint_url_is_current(api_base)
Try / catch
try:
resp = await client.request(...)
except HTTPClientException as e:
msg = str(e) # 'status=..., body=...'
status = int(msg.split('status=')[1].split(',')[0])
if status == 429: schedule_retry_with_backoff()
elif status in (401, 403): refresh_credentials()
else: alert_upstream(status, msg) Prevention
- Always parse the embedded body for the upstream error cause
- Implement backoff on 429/5xx, credential refresh on 401/403
- Alert on persistent 5xx to catch upstream outages
When it happens
Trigger: Any downstream/ASE service returning 4xx/5xx — bad request payload, 401/403 after auth, 404 wrong path, 429 rate limit, 5xx server errors.
Common situations: Malformed request body/schema mismatch, exhausted quotas, upstream outage or deploy breaking the API contract.
Understand the failure class
Background: "API error: {status}" and "HTTP 401/403/404/429/5xx" errors: non-2xx HTTP responses explained — this error's family across 27 libraries.
