What does "errors" of Twitter API's error response mean - twitter

Question

Twitter API's error response is something like this.
{"errors":[{"message":"Sorry, that page does not exist","code":34}]}
But I don't know why the key name (errors) is plural form and the value is an array.
I have never seen multiple errors are listed on this array.
Are there any case? If it be, tell me how you send a request.

The error above usually means the user/object you called the API on does not exist. Occasionally, it's a transient error but mostly it's because the object has been deleted.
As for seeing "errors", I've seen it in quite a few places. Twitter error handling seems to be all over the map. Twitter usually, not always, returns JSON in content in error cases , which provides more data.
Copy-pasting part of python code (in progress) dealing with some "errors". Please ignore the RR_XXX since those are mappings to internal error codes for my app.
status = resp['status']
if not status == '200':
errJson = json.loads(content) //Handle "ValueError" with try-except
if 'error' in errJson:
# HTTP-401: {"request":"...", "error":"Not authorized"}
err_code = RR_TWITERR_NOT_AUTHORIZED
elif 'errors' in errJson:
errors = errJson['errors']
sub_code = errors[0]['code']
if sub_code == 88:
# HTTP-429: {"errors":[{"message":"Rate limit exceeded","code":88}]}
err_code = RR_TWITERR_RATELIMIT_EXCEEDED
elif sub_code == 130:
# HTTP-503: {"errors":[{"message":"Over capacity","code":130}]}
err_code = RR_TWITERR_OVER_CAPACITY
**elif sub_code == 34:
# HTTP-404: {"errors":[{"message":"Sorry, that page does not exist","code":34}]}**
err_code = RR_TWITERR_NOT_FOUND
elif sub_code == 32:
# HTTP-401:[{u'message': u'Could not authenticate you', u'code': 32}]
err_code = RR_TWITERR_NOT_AUTHENTICATED
elif sub_code == 63:
# HTTP 403:{"errors":[{"code":63,"message":"User has been suspended."}]}
err_code = RR_TWITERR_USER_SUSPENDED
elif sub_code == 131:
# HTTP-500:{"errors":[{"message":"Internal error","code":131}]}
err_code = RR_TWITERR_INTERNAL_ERROR

err_code = RR_TWITERR_UNKNOWN

err_code = RR_TWITERR_UNKNOWN
return err_code
