Error message

response code is {response.status}

What it means

AppAuthFailedExc raised in app_detail when the auth service responds with a status other than 200. Note the literal string 'response code is {response.status}' is missing the f-prefix, so the actual status code is not interpolated — the developer always sees the placeholder text.

Solutions

  1. Fix the missing f-prefix in the raise so the real status is logged: f"response code is {response.status}"
  2. Check the auth service URL and credentials in configuration
  3. Verify the app_id exists and is accessible from this space
  4. Check auth service health/logs for the non-200 response cause

Example fix

# before
raise AppAuthFailedExc("response code is {response.status}")

# after
raise AppAuthFailedExc(f"response code is {response.status}")
Defensive patterns

Strategy: try-catch

Validate before calling

r = requests.get(auth_url, timeout=10)
if r.status_code != 200:
    logger.warning("app detail returned %s", r.status_code)

Try / catch

try:
    detail = await auth.app_detail(app_id)
except AppAuthFailedExc as e:
    logger.error("app auth failed: %s", e)
    return None

Prevention

When it happens

Trigger: Calling the app-auth detail lookup when the remote auth service returns 4xx/5xx (after raise_for_status passes or for non-200 success-range codes), e.g. app not found, auth service error, or wrong app_id.

Common situations: Misconfigured auth service URL; invalid/expired service credentials; auth service outage returning 500; querying a deleted or wrong-space app_id.
