@roamye This is going to be repurposed. The endpoint to retrieve data constants can be removed from the middle tier.

@kamerynB - is there any UAT links for this? Or are all records supposed to contain working as it has previously?

[kamerynB]

@roamye You can hit the middle tier directly here and see that the link no longer works. This was done once the AAT issue was completed as data constants are no longer required.
