OIC Gen2 Lookup REST API - All of a Sudden "Unauthorized 401" Error
*****Summary:
We have been using the 'Export a Lookup' REST API below without any issue - so we have been executing this API for a long time (which is also in our SIT & Production instances). All of a sudden, it starts to throw the "Unauthorized 401" Error and this is only happening to the Development instance, not in SIT nor Prod instances. The OIC Connection is using 'Basic Authentication' across all 3 instances (same configuration) and the credentials are perfectly ok (there has not been a change/update on credentials).
Do you think a latest patch/change on OIC Dev backed triggered this? I have no access to this patching/update information but just curious if that may have caused it, as good to note that other OIC REST APIs are still working fine, just this Lookup one is getting such error.
