Hello,
We found the issue but it turns out that it had nothing to do with my script.
One of our users had entered in a new host (A/PTR, DHCP records) via the web
user interface. However, he had also added a location record (LOC record).
Apparently, having a location record assigned to a DNS entity breaks the Netdot
exporter scripts for the entire zone file that the host is in. Apparently this
script places a lock on each of the database tables as it exports.
This seems like it is a bug in the Netdot code that the developers should look
into.
Thanks,
-------------

Hi guys,
I am currently experiencing a strange issue. I have a script that does a POST
request to the /rest/host interface to create a host with a DNS name and DHCP
allocation. I am currently using a python library that someone on the netdot
team made a while ago ( I?ve needed to modify slightly due to errors in their
code). That library is https://github.com/frgray/netdot-client-python.
So now to the issue. This script has worked well for months. Today, however, it
has decided to stop working. I did not make any changes to the netdot
configuration or my script. I turned on the debug mode and am getting a 400 bad
request error, as seen at the bottom of this email. I can see that the script
successfully authenticates to the page. I checked logs and also saw the below
log entries. Any ideas? Thanks in advance.

Can you be more specific on how it breaks? Any error messages, logs, etc?
