Last Object in Array Goes Missing

[A]

Need suggestions, going crazy here

I am missing my last row of my object array called: data

console.log(data) //has 80 rows

Users.find({"_id": {$in: ids}}, {'_id':1, 'Fullname':1}, function(err, results) {  //i've used this query numerous times thought the whole site, nothing new

    console.log(data) //has 79 rows

      //... i do some stuff, but doesnt really matter ...//

});

                

Right after I run the mongoose  Users.find, the last element disappears; makes no sense to my why.  This happens every time, for every instance of the code run

I do have some code above it and after it, but I narrowed it down to these 3 lines.  Any Ideas? suggestions?  Row counts vary between execution

I take it back

i have a function after it that calls a splice of an index of -1, which seems like it gets rid of the last element

My other environments work because the index was >0 (search for specific index, where -1 was not found)

Back to sanity

Some additional notes

Works fine in Test and Dev but not Prod, so the code is fine

Where is data defined? It is hard to tell from the limited context what else touches it.

Remember that your callback is being called after Users.find() returns, so if you are modifying that data array in any lines after that call to Users.find(), they will modify the data before your console.log() it the second time.

If the rowcount changes each time you run the procedure it must be your data?

I got it solved; looks like my 2nd reply came in late; the first one where I mention the splice was what solved the issue

I narrowed it down to those lines was incorrect because of async.  My console.log (really a diff custom function) writes to db vs console; so the delay on that made it seem at that moment the data was getting lost, but in actuality, that function finished and went on to another function before even the second log event ran
