Error message
"Authentication Error, " + str(e)
What it means
The non-HTTPException branch of /user/update's error wrapper: every plain exception becomes ProxyException 'Authentication Error, <original message>' with type auth_error and code 400. Common underlying causes are ValueError 'Either user_id or user_email must be provided', Exception 'Not connected to DB!', and Prisma/database errors. The 'Authentication Error' prefix is cosmetic - the real cause follows the comma.

Solutions
- Read the message after 'Authentication Error, ' - it names the real error (e.g. 'Not connected to DB!' or the ValueError text)
- Fix that root cause: add user_id/user_email, configure general_settings.database_url, or repair the database
- Check exception-level proxy logs for the full stack trace of the original exception
Example fix
# before: 400 'Authentication Error, Either user_id or user_email must be provided'
POST /user/update {"user_alias": "x"}
# after
POST /user/update {"user_id": "u1", "user_alias": "x"} # 200 Defensive patterns
Strategy: try-catch
Validate before calling
def update_payload_ok(payload: dict) -> bool:
return bool(payload.get("user_id") or payload.get("user_email")) # avoids the ValueError wrap Try / catch
except requests.HTTPError as e:
body = e.response.text if e.response is not None else ""
m = "Authentication Error, "
if e.response is not None and e.response.status_code == 400 and m in body:
real_cause = body.split(m, 1)[1] # e.g. 'Not connected to DB!' or the ValueError text
# handle the real cause, not an auth problem
... Prevention
- Strip the 'Authentication Error, ' prefix before routing errors in your handlers
- Pre-validate identifiers and DB connectivity to avoid the wrapper entirely
- Capture proxy logs alongside client errors - the wrapper hides the stack trace
When it happens
Trigger: POST /user/update that hits a non-HTTP failure: body missing both user_id and user_email (ValueError), no database configured ('Not connected to DB!'), or a Prisma error during the update write.
Common situations: Developers chasing a phantom authentication problem that is actually a payload or DB config issue; CI environments without Postgres where every update fails this way.
Understand the failure class
- Authentication and authorization failures — expired tokens, bad credentials, and missing scopes.
