How to fix TypeError: Cannot set property 'address' of undefined?

Question

JavaScript

I catch an error - TypeError: Cannot set property 'address' of undefined
I understand the essence of the error, at a certain iteration of the loop the variable is not defined.
In a loop, a variable always has a value, only at the end it doesn't. How to fix?
Tried to catch values ​​with the help of conditions, does not help.

query_region.find({}, function(err,getoverhaulhouselistbyaoguids){                           
                                             var i = 80;
                                             var z = 97;
                                             for(var l = 0; l < i; l++){
                                                 for(n = 0; n < z; n++){
                                                          if(getoverhaulhouselistbyaoguids == undefined){

Answer 1

You misunderstand. You do not have the address variable not defined, but some object in which you want to assign the address. In fact, the error message usually contains the filename and line number.
In any case, look for an error in the line of the form
AND find out why your obj is not defined.

Answer 2

make more classes in the internal policy of XXX-Video and let telemetry be in priority, and video conferencing in a guaranteed bandwidth, tk. Videoconferencing is easier to survive jitter than telemetry:
class-map match-all telemetry
... whantever ...
!
policy-map XXXX-Video
class telemetry
priority 2000
class Video-any
bandwidth 2000
class class-default
fair-queue
!

Answer 3

Something like this. Define separate classes for the required traffic. If there is telephony, then be sure to use priority. it activates LLQ, which is important for telephony. For other classes, cut strips as needed.
class-map match-all REALTIME-DATA
match ip dscp ef
class-map match-any CRITICAL-DATA
match ip dscp cs3 cs6
class-map match-any IPTV
match ip dscp cs4
policy-map OUT-POLICY
class REALTIME-DATA
priority percent 5
class IPTV
bandwidth percent 60
class CRITICAL-DATA
bandwidth percent 20
random-detect dscp-based
class class-default
random-detect dscp-based
