My guess is that your issue likes in the way you are using Q/promises. A query
from a DB is typically an asynchronous operation, so while step 3 is waiting on
a response step 4 will run, and when that is waiting for a response, the last
step will be executed. Using Q will indeed help you make them run in sequence.
If you can can share the relevant code we can try to figure out what’s off.
